Does mass affect the acceleration of an object in free fall





please give a sourceDoes mass affect the acceleration of an object in free fall?
if we are neglecting air friction, then mass has no effect on the rate of acceleration; all objects will accelerate near the surface of the earth at the rate of 9.81 m/s/s





the first answer is self-contradictory; aerodynamics will matter only if we consider the interaction between the moving object and air, and if we are considering those interactions, then the mass will certainly matter as well as the shape of the objectDoes mass affect the acceleration of an object in free fall?
Nope. Gravity and aerodynamics (the shape) will.





All objects (masses) fall (accelerate) to earth at the same rate, however, due to air resistence (friction) between the mass and the surrounding fluid (air) some will be slowed.





This is why a piano will hit the ground before a feather. The feather is aerodynamic (designed that way so birds can fly), and so there is higher pressure around it (just like an airplane wing), while the box-like piano is not aerodynamic and so it has lower pressure around it.





So, it is interesting to think that a 600 lb. piano will hit the ground before a 1000 lb. feather would. Yeah, that would be one big bird (hum, what is like a big bird and weighs a lot more than a piano? A plane!)
