Question

Give reasons -
A crumpled ball of aluminium foil falls with greater speed than a sheet of same size.

Answer 1

heya , user !!!

While falling, both the sheet of paper and the paper ball experience air resistance. But the surface areaof the sheet is much more than that of the spherical ball. And air resistance varies directly with surface area. Hence the sheet experiences more air resistance than the ball and it falls more slowly than the paper ball

hope that helps
