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.
