If an object has no acceleration is it safe to say that no forces are acting upon it?

Plz help me!!!








Answers must be 3-4 sentences!! =) Thank You!!If an object has no acceleration is it safe to say that no forces are acting upon it?
rest your pencil on the table.... it isn't moving, right? it would appear no acceleration is being applied to it, and no forces are acting upon it.





but we know that's not correct.


- there is a gravitational force that is being applied to it.


- there is the upward force of the table being applied to it also so it doesn't fall.





what happens here is that the forces balance out, so there is no NET acceleration, but there are indeed many (balancing) forces acting upon the pencil...If an object has no acceleration is it safe to say that no forces are acting upon it?
No!


It has potential energy.
3 to 4 sentences? Jeez. If you are standing still you are not accelerating but you have the force of gravity pulling you keeping you on the ground. Hope that helps get you started
No, it just means the forces are in equilibrium. For example, gravity is always affecting you, but the ground is exerting an equal and opposite force called the Normal Force.

  • How can you find the mass of an object?

    Using a beam balance.


    Or use formulaes. For eg, Mass=Volume X Density.How can you find the mass of an object?
    Put it on a balance.How can you find the mass of an object?
    It's easy, just use the formula mass/volume!
    well you look to the lower half of the body..usually situated on the lower back..they are 2 mounds of flesh...ohhhhh mass

    Looking for a fish game - kind of hidden object game?

    I played the game before but I can't find it anymore:( It was where you go down in the ocean and the timer is your air tank I think. You have to take pictures of certain kinds of fish to get points.Looking for a fish game - kind of hidden object game?
    Oddly, I don't remember the name and yet I know where the game is, lol. It's on http://www.bigfishgames.com/





    I did a trial download of the game from that site (a site I have used and trusted for nearly three years) but didn't buy the game. I'm sorry I can't recall the name. If you like Hidden Objects games, as I do, the best I've found is the Mystery Case Files series, especially their Prime Suspects game. (They also have Huntsville Alabama, Ravenhearst, and I believe a fourth one that I didn't like as much. I far preferred Prime Suspects and Ravenhearst.)

    If you double the weight of an object, will it's acceleration be twice as large or half as large?

    This is in the absence of friction and other forces.... thanks in advance.If you double the weight of an object, will it's acceleration be twice as large or half as large?
    weight = mg





    F = ma


    mg = ma


    a = mg / m = g





    for weight = 2mg


    F = ma


    2mg = ma


    a = 2mg / m = 2g





    2g is 2 times greater than g, so it doubles the acceleration.





    Note, this is only true if you double the g constant, not the mass, because the mass cancels when solving for a. You can see this easily, if you drop a 1 pound ball and a 2 pound ball, both accelerate at the same rate. If you were to drop a 1 pound ball on the moon and on the Earth, you would see the ball accelerates more quickly on the Earth because g for earth = 9.8 and g for the moon = 9.8/6If you double the weight of an object, will it's acceleration be twice as large or half as large?
    Your question is not clear. If you are dropping a two pound weight and a four pound weight, the acceleration will be the same. In this case the force is not fixed.





    If by weight, you mean mass, and your force is constant, then the acceleration will be cut in half.





    If the weight is doubled by doubling gravity, then the acceleration will double.





    Is there a chance you are confusing 'weight' and 'mass'?
    I believe F = MA would be the equation to use. Assuming that the force stayed constant, the acceleration would be half as much if the mass doubled.





    Solving for A, A = F/M , so, If the new mass was twice the old mass, the new acceleration would be half.

    An object moving a 30 m/s to the right begins to accelerate at 5 m/s^2 to the left for 3 seconds.?

    Then the question is. What is (a) the displacement and (b) the velocity of the object after 3 seconds? (Include direction in your answer.)





    I need help on this physics question because my physics teacher isn't really good at teaching us haha. Well please help and thank you.An object moving a 30 m/s to the right begins to accelerate at 5 m/s^2 to the left for 3 seconds.?
    If your object is moving to the right and it undergoes an acceleration to the left, this is a negative acceleration - the car is slowing down. Using basic motion equations we can solve this problem. Let's identify what variables we need that the question gives us:





    Acceleration = - 5 m/s^2


    Time = 3 s


    Initial velocity = 30 m/s [right]


    Final velocity = ?


    Displacement = ?





    For a), we need to solve for displacement.


    Displacement = (initial velocity)(time) + 0.5(acceleration)(time)^2


    = (30 m/s [right])(3 s) + 0.5(- 5 m/s^2[right])(3 s)^2


    = 90 m [right] + (-22.5 [right])


    = 67.5 m





    For b), we need to solve for the final velocity after it has travelled this far.





    final velocity^2 = (initial velocity)^2 + 2(acceleration)(displacement)


    = SQRT (30 m/s [right])^2 + 2(- 5 m/s^2[right])(67.5 m)


    = SQRT (900 m/s [right] + (- 337.5 m/s [right])


    = SQRT 562.5 m/s [right]


    final velocity = 23.72 m/s [right]





    The SQRT mean you must take the square root of whatever your answer in brackets is since the variable we are solving for is squared.


    These equations are given to you in grade 11 I believe - it's best to memorize 'em!

    An object is thrown vertically into the air?

    An object is thrown vertically into the air. Because of air resistance, the time for its descent will be:





    longer than the ascent time.


    shorter than the ascent time.


    equal to the ascent time.


    not enough information given to sayAn object is thrown vertically into the air?
    equal to the ascent time.An object is thrown vertically into the air?
    In general the descent time will be longer. When the object is launched at some speed v it is slowed down by gravity and air resistance. When it stops at its highest point and begins to fall gravity works to speed it up while air resistance fights to slow it down.





    Thus on the way up both are working to slow it down (maybe it slow down and stop quickly). On the way down the two fight each other and the object accelerates slower (thus taking longer to return to the surface).





    I hope that helps!

    An object with a charge 4 C and a mass 0,5 kg accelerates from rest to a speed of 21 m/s.?

    An object with a charge 4 C and a mass 0,5 kg accelerates from rest to a speed of 21 m/s.





    1. Calculate the kinetic energy gained. Answer in units of J.





    2. Through how large a potential difference did the object fall? Answer in units of V.An object with a charge 4 C and a mass 0,5 kg accelerates from rest to a speed of 21 m/s.?

  • An object that has potential energy may have this energy because of its what?

    Well it depends on what kind of potential energy we are talking about. Potential energy is not just due to your height(more specifically your position in a gravitational field) but also there is electro magnetic potential energy (which is the energy due to your position in an electromagnetic field). So, you could say that potential energy is due to your position in any kind of field whether it be gravitational, electromagnetic, ....etcAn object that has potential energy may have this energy because of its what?
    Yes it is it's height/position. If it is say up in the air, it has potential energy because it could fall down, etc.An object that has potential energy may have this energy because of its what?
    height


    potential energy is energy due to position
    Because of it's position and configuration.





    There you go, I'm glad I could help. :)

    Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?

    I guess the question that I am asking is what if anything was before the universe. I can't get my head around there was NOTHING but then SOMETHING went bang.Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?
    It wasn't a bang. It was a fizzle of pure energy. What it expanded out into is sort of beyond our comprehension right now. But, everything that is this Universe, even the spacetime fabric and you and I, are actually composed of that initial 3 second fizzle of energy. Here is a real image that we have recently made of the beginning of the Universe. AND, here also is a real recording of the noise of that first fizzle:





    When you have some time, explore the second to last link at the bottom of the page in this article to see accurate models of how the Universe expanded:

    This is the radio static of that beginning fizzle:


    http://encarta.msn.com/media_461543080_1鈥?/a>Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?
    Sorry. As far as we can tell, it was nothing. If there was anything, it's outside of our universe, since we expanded into it. And we can't see outside our universe.
    speaks wonders for a creator,,,,set off a big bang..
    The questions in google asks seem to clump around various subjects,this one is probably the most speculative.


    Mathematics may never be applied with any success in this case.


    But language with the injection of semantics may give some ground on which to speculate and theorize.


    It may never get beyond this.
    The big bang was not an explosion but an expansion of time and space. Time started at the big bang so asking what was before the big bang is like asking what is north of the north pole.
    In the begining there was no space, time, energy, or matter. All the matter was in the form of a singularity with no dimension and near infinite mass. At the moment of the big bang all of the matter was converted to light. ';Let there be light'; For several seconds nothing existed but space, time and light. As the universe cooled the light converted back to matter.
    the big bang never happened

    Mysterious object over the space shuttle?

    do you guys think it was an ';alien'; a ufo, or simply ';tiles that protect the shuttle from overheating'; as nasa apperantly said, i dought its just tiles, tiles arent that big or round! what do you guys think? are we alone?Mysterious object over the space shuttle?
    We are not alone. Anyone who would think that in this whole, unmeasurable universe we, on Earth, are the only intelligent beings is totally unlogical. I don't know what they are viewing out of the space shuttle, but if it were something that ';fell off';, wouldn't that object just keep going, instead of keeping pace???Mysterious object over the space shuttle?
    An object in motion tends to stay in motion. 2 objects separated from a single initial object tend to share the same velocity (speed in the same direction.) In the absence of different accelerations between the objects, they would continue to share similar orbits. Report Abuse

    Probaly just some rubbish, or a big chunk of poop from the earlier rockets.
    Maybe it's pieces of ';trash'; from the defective air scrubber from the Russians. Someone left their tool box outside again. Hell, they were losing bolts and tools already with that addition they were working on. If it was alien I doubt they would talk about it. Wouldn't it be nice of them to rescue our Astronauts anyway? Show them what a real ship is made like? (oh boy)
    It was one of Madonna's implants
    Beats me. Will just have to wait and see when they get back. Hope it nothing, saw one shuttle explode, don't want to see another.
    It is in nearly the same orbit and appeared right after a small burn. Chances are it is something that shook loose during the burn. NASA probably wants to figure out what it is before they re-enter in case it indicates something that needs to be attached for successful re-entry (like a tile.)
    NASA just made the whole thing up to get more money from Congress.
    This is a good example that shows how confused people are at the term UFO. And as the first answerer noted, its not ';flying';: actually it's orbiting under no power. There are thousands of pieces of space junk orbiting the earth (see url). Lots of them bolts and nuts. So just because NASA or someone identifies something as a UFO doesn't mean it is something alien or mysterious. It might just be a nut.





    As opposed to the alien and mysterious nuts who claim it must be aliens.

    What is the Calue speed if an object is standing still? What is the value for Velocity? Momentum?

    speed= distance / time


    but distance is zero


    thus speed=0/time = 0!





    speed of still object is zero!








    velocity=displacement / time


    displacement is zero for still object


    thus velocity=0 /time = 0


    value of velocity is also zero!!








    momentum = mass X velocity


    but velocity is zero


    thus


    momentum = mass X (0)=0


    thus momentum = 0!!!

    What is the exact location of the object at time 3? Integrals question.?

    An object originally located at x=4. Beginning at time zero, the object moves along the x axis with velocity given by -5-2t+4t^2. Determine the exact location of the object at time 3. What is the exact location of the object at time 3? Integrals question.?
    displacement is integral of velocity





    v(t) = -5 - 2t + 4t虏


    s(t) = 鈭?5 - 2t + 4t虏 dt


    = -5t - t虏 + 4t鲁/3 + C





    Plug in known value


    s(0) = 4


    S(0) = -5(0) - (0)虏 + 4(0)鲁/3 + C


    4 = -5(0) - (0)虏 + 4(0)鲁/3 + C


    C = 4





    s(t) = 4 - 5t - t虏 + 4t鲁/3





    s(3) = 4 - 5(3) - (3)虏 + 4(3)鲁/3


    = 4 - 15 - 9 + 36


    = 16What is the exact location of the object at time 3? Integrals question.?
    v(t) = -5 -2t + 4t^2 = dx/dt integrate dx from 4 to final position and the time function from 0 to 3. So,


    INT{dx}from 4 to Xf = INT{-5 -2t + 4t^2} from 0 to 3


    Xf - 4 = -15 -9 + (4/3)*27


    Xf = -15 -9 + (4/3)*27 + 4


    Xf = 16


    So the object started at x = 4 and ended up at x = 16
    v(t) = 4t^2 - 2t -5





    Integrate to get:





    x(t) = (4/3)t^3 -t^2 -5t + C.





    C = x(0) = 4.





    x(t) = (4/3)t^3 -t^2 -5t + 4.





    x(3) = (4/3)(3)^3 -(3)^2 -5(3) + 4.





    I'll let you do the rest.



    plugging 3 into the equation you come up with x=25, so adding the original 4 to that x=29.
    25 (make a graph)

    It's impossible by definition. They can't possibly exist in the same universe, and only a contest between them could determine which is accurate. The definition of unstoppable means that nothing else is immovable, and vice versa.
    Nothing. It can't happen. There is no such thing as an unstoppable and unmovable object. Everything has it's own strengths and weaknesses.

    What is the buoyant force of an object that weights 35N displaces water that weighs 25N?

    please explain too please!!What is the buoyant force of an object that weights 35N displaces water that weighs 25N?
    The buoyant force is 25N.





    The weight of the water displaced is equal to the buoyant force. This is sort of Archimedes' principle for dummies. To get this object to float you would have to modify its shape to get it to displace more water (at least 35N worth). To demonstrate this you could take some foil, make a boat and add some weight. Place the boat in the water and it will float. Then take the foil and crumple it up around the weight. You now have exactly the same MASS as before but when you place it in the water now it will sink. This is because you modified the VOLUME. When it was shaped like the boat it displaced more water (more water displaced means more buoyant force to push up on the boat). I hope this helps. Let me know if you need clarification or more detail.

    An object that has potential energy may have this energy because of its what?

    Well it depends on what kind of potential energy we are talking about. Potential energy is not just due to your height(more specifically your position in a gravitational field) but also there is electro magnetic potential energy (which is the energy due to your position in an electromagnetic field). So, you could say that potential energy is due to your position in any kind of field whether it be gravitational, electromagnetic, ....etcAn object that has potential energy may have this energy because of its what?
    Yes it is it's height/position. If it is say up in the air, it has potential energy because it could fall down, etc.An object that has potential energy may have this energy because of its what?
    height


    potential energy is energy due to position
    Because of it's position and configuration.

    Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?

    I guess the question that I am asking is what if anything was before the universe. I can't get my head around there was NOTHING but then SOMETHING went bang.Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?
    It wasn't a bang. It was a fizzle of pure energy. What it expanded out into is sort of beyond our comprehension right now. But, everything that is this Universe, even the spacetime fabric and you and I, are actually composed of that initial 3 second fizzle of energy. Here is a real image that we have recently made of the beginning of the Universe. AND, here also is a real recording of the noise of that first fizzle:

    http://encarta.msn.com/media_461543080_1鈥?/a>Assuming that the Big Bang Theory is correct, what was the medium that the object/s that exploded sitting in.?
    Sorry. As far as we can tell, it was nothing. If there was anything, it's outside of our universe, since we expanded into it. And we can't see outside our universe.
    speaks wonders for a creator,,,,set off a big bang..
    The questions in google asks seem to clump around various subjects,this one is probably the most speculative.


    Mathematics may never be applied with any success in this case.


    But language with the injection of semantics may give some ground on which to speculate and theorize.


    It may never get beyond this.
    The big bang was not an explosion but an expansion of time and space. Time started at the big bang so asking what was before the big bang is like asking what is north of the north pole.
    In the begining there was no space, time, energy, or matter. All the matter was in the form of a singularity with no dimension and near infinite mass. At the moment of the big bang all of the matter was converted to light. ';Let there be light'; For several seconds nothing existed but space, time and light. As the universe cooled the light converted back to matter.
    the big bang never happened

    Mysterious object over the space shuttle?

    do you guys think it was an ';alien'; a ufo, or simply ';tiles that protect the shuttle from overheating'; as nasa apperantly said, i dought its just tiles, tiles arent that big or round! what do you guys think? are we alone?Mysterious object over the space shuttle?
    We are not alone. Anyone who would think that in this whole, unmeasurable universe we, on Earth, are the only intelligent beings is totally unlogical. I don't know what they are viewing out of the space shuttle, but if it were something that ';fell off';, wouldn't that object just keep going, instead of keeping pace???Mysterious object over the space shuttle?
    An object in motion tends to stay in motion. 2 objects separated from a single initial object tend to share the same velocity (speed in the same direction.) In the absence of different accelerations between the objects, they would continue to share similar orbits. Report Abuse

    Probaly just some rubbish, or a big chunk of poop from the earlier rockets.
    Maybe it's pieces of ';trash'; from the defective air scrubber from the Russians. Someone left their tool box outside again. Hell, they were losing bolts and tools already with that addition they were working on. If it was alien I doubt they would talk about it. Wouldn't it be nice of them to rescue our Astronauts anyway? Show them what a real ship is made like? (oh boy)
    It was one of Madonna's implants
    Beats me. Will just have to wait and see when they get back. Hope it nothing, saw one shuttle explode, don't want to see another.
    It is in nearly the same orbit and appeared right after a small burn. Chances are it is something that shook loose during the burn. NASA probably wants to figure out what it is before they re-enter in case it indicates something that needs to be attached for successful re-entry (like a tile.)
    NASA just made the whole thing up to get more money from Congress.
    This is a good example that shows how confused people are at the term UFO. And as the first answerer noted, its not ';flying';: actually it's orbiting under no power. There are thousands of pieces of space junk orbiting the earth (see url). Lots of them bolts and nuts. So just because NASA or someone identifies something as a UFO doesn't mean it is something alien or mysterious. It might just be a nut.

    Have you ever seen an unidentified flying object?

    I was driving to work here in sunny FL. Day had clear skies with no clouds. I looked up and say a metalic looking disc flying towards me. It then turned on its side, making it look like a shield, and darted off really fast. I noticed birds and a plane, and this thing did not look like either. It probably happened in a 2-3 second span. I'm not crazy and I know exactly what I saw. Anyone else seen anything like this?Have you ever seen an unidentified flying object?
    nope but i would love to see something like thatHave you ever seen an unidentified flying object?
    Yes, I have seen an unidentified flying object. I couldn't identify it. Without going into long descriptions of what it looked like or how it behaved, it turned out to be a hot air balloon flying dangerously low over an oil refinery in the dark - the ';pulsating object'; I could see was light from the burner reflected of the bottom of the envelope.

    What is the Calue speed if an object is standing still? What is the value for Velocity? Momentum?

    speed= distance / time


    but distance is zero


    thus speed=0/time = 0!





    speed of still object is zero!








    velocity=displacement / time


    displacement is zero for still object


    thus velocity=0 /time = 0


    value of velocity is also zero!!








    momentum = mass X velocity


    but velocity is zero


    thus


    momentum = mass X (0)=0


    thus momentum = 0!!!

    Go to an optometrist. What you describe is characteristic of astigmatism,at least in perceiving static patterns.

    Why is it no one ever accuses men of reducing themselves to a ';sex object';?

    whether from working in the sex industry, or simply engaging in casual, anonymous sex? When women do these things, people warn her that it's ';degrading'; because the other people don't really care about her as a person, but just see her as a ';sex object'; or are ';using her.'; So how come we don't warn men about how they're ';degrading'; themselves, and mankind as a whole? Does this suggest that we give men a lot more freedom when it comes to their sexuality than we afford women? Do we consider men more capable of handling their sexuality and perhaps being what some people would consider more reckless with it?Why is it no one ever accuses men of reducing themselves to a ';sex object';?
    I'm just thinking out loud here...





    Your question is as old as Snow White. What DID Snow White do? Oh, yeah, she cleaned, cooked, croaked and some charming young man charmed the panties off her and they got married and lived happily ever after. Pretty passive, don't you think? Passive is bad, it takes one to aggressive behavior eventually. Assertive would be better. Yet this is what we teach our kids... and this is where this all starts.





    Society is obsessed with woman's status. Is she married? Is she single (virgin)? Is she divorced? Just think of this example - man is always Mr. - complete whether alone or married. Woman can be Miss, can be Mrs. can be Ms... but why?





    Forgive me for being blunt, but p-u-s-s-y is power to those women who know how to use it against those men who let their lives be ruled by it. Lisistrata is a great example - when Spartan and Athenian women got so sick of their husbands fighting that they told them they would get no sex until they stopped the war. Classic Greek comedy with a very clear message - ';The man may be the head, but the woman is the neck!'; (My Big Fat Greek Wedding)





    And, there's the law of supply and demand. Men want it, they make more money, so they have to pay less fortunate women to get it. The kinds of men who go to strip bars and whore houses have problems being around women in the real world because they are afraid of them (fear of the unknown - which is very curable).





    We've been called the second sex, the weaker sex, the fair sex for too long. It's time we give credit where credit is due. We're the stronger sex because we aren't afraid to meet a man and fall in love. That's why most of us don't go to male whore houses or strip bars. Supply and demand at work again.





    If you really want to go back in history I recommend ';When God Was a Woman';. You will understand why, for two thousand years, women have had to suffer due to some supposed sin some Eve committed. Of course, Lilith came first, but the Bible killed her and her myth.





    Before Judaism (and Christianity), women were considered equals to men - sex and all. So, you ask why; the Bible, that's why.Why is it no one ever accuses men of reducing themselves to a ';sex object';?
    Probably goes towards the quality of the sex they are having. If one half of the (assuming 2 people) party is banking their chip's but the other is thinking about the weather, then the latter is a sex object as oppossed to a loooove maker.





    So in that regard I dont think their is anything wrong with being a sex object, might not be preferred but at least your 'at' the party.





    Some people believe that when having sex you connect spiritually with the person in a long term way that is generally inpercievable - some form of soul relationship is formed which remains for quite a while. So if that were true then having sex for cake but not the presents could be considered muddying your spiritual energy and therefore degrading of your true inner purity. I personally do not have enough experiance to support that but would be happy to undertake exhaustive research on it :)
    Do you find any of these men appealing?


    http://www.youtube.com/watch?v=oeikk3sXl鈥?/a>
    If someone did accuse me of that it wouldn't worry me at all, I know I am a good person and don't really care what other people think. Unless they are close to me that is then you listen to what they think.
    Because they're seen as the ones that prey on sex objects. And if we were to call them sex objects... they most-likely wouldn't take offense to it. I feel as though it's more accepted for men to have sex with whoever, but that doesn't mean I think it's okay. Everyone should have respect for themselves.





    You're right... the way men act these days is disgusting, they all seem like pigs, they don't realize that they really are degrading mankind.
    You do realize that men and women have an evolved heritage that effects their behavior in the world of here and now, don't you?





    Sorry. I am used to speaking with evolutionary scientists who are cognizant of the evolved variation in reproductive strategies that carry men and women apart in their proximate behavior. Women in all cultures are seen as the '; goal '; of male reproductive strategy, to a greater or lesser degree. While women are seen as those who chose mates by being choosy. Both sexes were '; designed '; to compete for mates, just in a different way. A good popularization of this evolutionary concept would be, '; The Evolution of Human Sexuality ';, by Donald Symons. Not too technical and rather short of mathematical paraphernalia.


    This rather applies to perceptions humans have. Not that a description of what is, is a prescription of what to do, but a '; heads up '; on cause. That distinction needs be made in this section.


    By the way, scientists do have opinions, but this is not one of them. The work done here is quite empirically supported.





    '; cult of scientism??? '; Spoken like a truly ignorant, relativistic, post-modern Canadian harridan. Keep it up and you will have to get a new account before the end of the weak, babushka.
    I think it's not quite accurate to say that no one thinks of men as reducing themselves to ';sex objects.'; There are men who definitely do this, and it's not any less demeaning for them as it is for women.





    I guess what it comes down to is this: we have the freedom to make choices based on our own personal beliefs and sets of morals or values or ethics. What we choose for ourselves is something we must live with. What feels comfortable or right to one person may be wrong or distasteful to another. I don't believe in imposing our own beliefs onto others, as long as no one's getting hurt by our choices. (Including us!) We are all individuals, but our individual choices can and do affect others...including society. I just have to wonder, how often does the average joe think about society when making personal choices? Probably not very often. We tend to see things from only our own perspective. I suppose that's what comes naturally to most. What I'm suggesting is that we look beyond the scope of the here and now, and beyond ourselves, and see the bigger picture. It's hard to do this, sometimes.
    I'd like to be a sex object.
    I have in the past told men who abuse women not to lower themselves, and that such behavior is unmanly. (I used to work with sex offenders and other human-service populations.) I believe this is an equivalent to the case you offer above. Both concern the perversion of a primitive power that one sex has over the other being put to desperate use, often because of the lack of other, more appropriate, civilized empowerment skills.


    ___I think that men hear less of this because this approach is too sympathetic. The custom in America is for the society to want to shame male abusers as much as possible, regardless of whether it accomplishes any rehabilitative function. But it is not the same for women who exploit their sexual powers.
    Just ignore jonmcn - he belongs to the cult of 'Scientism' and gets confused very easily. You have probably noticed by now that he has 3 stock answers that he uses to answer any and every question - in all categories. Blustering and full of himself, he is a mindless robot.





    ';Does this suggest that we give men a lot more freedom when it comes to their sexuality than we afford women? ';


    Why YES, and it's always been this way. The less power the woman has in a society (as in Agrarian societies) the more repressive and the more restricted her behaviors, sexual and otherwise. Afghanistan would be a good example of an Agrarian society - it's not urbanised, and most people make their living off the land. Anyway, the sexual repression of women is just one piece in a much larger mosaic of sexism.
    Good question. I'm a stripper as well and yeah, when I'm at work, maybe some (neanderthal) customers view me as a simple sex object. But I also view them as a monetary object-they're not ';people'; when I'm at work, they're walking ATMs. When you go to a restaurant, do you look at your waitress and go ';oh, she must be such a nice person! I wonder what her hopes and dreams are';? No, you don't care, you just want your food. You're viewing the waitress as an object there only to serve you your food. What's the difference?


    ';Does this suggest that we give men a lot more freedom when it comes to their sexuality than we afford women?'; Oh yeah. The strip club is a perfect example. Remember a few years ago when a college student was expelled for being a stripper because a group of guys from her school saw her there? Yeah, those guys weren't kicked out..it was OK for them to go to the club but it wasn't OK for her to work there. ::bangshead::
    im fifty years old, balding and showing the obvious effects of raising two teenage children...PLEASE REDUCE ME TO A SEX OBJECT...IT WOULD BE THE BIGGEST ACHIEVEMENT PERSONALLY FOR ME IN SOME TIME....





    the idea here is simple. women are the beauty of the world and men obsess about it...deal with it. its nature.
    We have always given men more freedom in this area the we have women. That was one of the things women's lib was suppose to deal with and change. Guess that tells us it is still a mans world!!
    Or maybe some disgruntled female, no less discontent then some males, see a male as nothing less than mere sex object? I think it occurs in both directions sometimes.
    The notion of an 'object' implies passive participation in the act. The 'object' is the receiver of an action from the 'subject.' The man is f(*#ing the woman, not the other way around. Therefore the woman is the one who is being objectified.





    I think the closest comparable phenomenon in the reverse direction is when women compete with each other over the worth of the man they're with. In this case each woman has ';caught'; a man... Therefore the woman is the subject, the actor, the one who did the catching... And the man is the object.





    And I think you do hear men complain about... The complaints just aren't seen as particularly noteworthy. The general opinion is that, since men don't have to deal with the glass ceiling and aren't generally expected to take an equal part in child-rearing, they should darn well shut up and accept the fact that they're regularly viewed as 'breadwinning' objects.
    No idea. Its the same idea when you say that when a woman sleeps with many men, she's a slut, but when men sleep with many women, he's a Pimp .. Quite annoying.
    As I said in your other thread, I also wonder why nobody complains about males acting as slaves in BDSM porn where a female dominatrix is doing grotesque things to them.





    Let's face it. People think all guys are sexual beasts and that it's a reward for them to be having casual sex, being a porn celebrity, etc, etc. I think people rely on the evolutionary theory and will say that men can't control themselves at the sight or thought of a sexual woman, while women don't care if they see a naked male porn star (which isn't true).





    I don't think some people on yahoo especially can accept that women can be just as sexual, that women can use men as sex objects, etc. What disappoints me is when other women think this way. I can see why an uniformed teenage boy may think that some women can't enjoy casual sex or something wild and kinky....but how can other women accuse us of not liking these things and how porn is only a man thing?
    I've been trying like hell since puberty but the label just doesn't want to stick..........
    i, personally, thing it degrades their character regardless of being male or female. it's pretty gross %26amp; shows a lack of respect for oneself, imo.





    but hey, another one of those unexplainable double standards.
    The whole sex object thing was brought up as a complaint by feminists. People see women as degrading themselves as sex objects because that is what feminists labeled them as in order to make men feel guilty. Next you'll be saying that people saying women are objectified all the time (by men) is evidence that women are discriminated against.

    Why didn't Nefertiti and Rory Emerald object to Smenkhkare and Akhenaten being lovers?

    Smenkhkare, Akhenaten's successor and/or co-ruler for the last years of his reign. Rather than a lover, however, Smenkhkare is likely to have been a half-brother or a son to Akhenaten. Some have even suggested that Smenkhkare was actually an alias of Nefertiti or Kiya, and therefore one of Akhenaten's wives. Montet describes Smenkhkare as Akhenatons' son-in-law, husband of his eldest daughter, who would by custom have conveyed him the succession (which was via the female line).





    However, Tiy, his mother was one suspect of being Akhenaten's lover. Twelve years after the death of Amenhotep III, she is still mentioned in inscriptions as Queen and beloved of the King. It has been suggested that Akhenaten and his mother acted as consorts to each other until her death. This would have been considered incest at the time. Supporters of this theory (notably Immanuel Velikovsky) consider Akhenaten to be the historical model of legendary King Oedipus of Thebes, Greece and Tiy the model for his mother/wife Jocasta. Mainstream Egyptologists do not take these speculations seriously.Why didn't Nefertiti and Rory Emerald object to Smenkhkare and Akhenaten being lovers?
