Question

Two large sheets of aluminium foil identical in size and shape are taken. One sheet is
crumbled into a tight ball and other sheet is kept as such. Now both the ball and sheet of foil
are allowed to fall through air from same height and at the same time.
a) Which piece of foil falls with greater speed and why?
b) What force comes into play when an object moves through air and on what factor docs it
depend?
c) Why are the objects/bodies moving through fluids given special shapes?​

Answer 1

They think that gravity acts more on a heavier object thus pulling it down faster. In fact, gravity works independently of mass. This means that all objects should fall at the same rate. ... If there is no air resistance, or the same amount of air resistance, then objects of the same mass will fall at the same rate
