Question

A crumpled piece of paper hits the ground before a flat sheet of paper because

Answer 1

The reason the crumpled paper hits the ground first is because of air resistance. A crumpled piece of paper has less surface area than an piece of paper that is not crumpled. More surface area means more air resistance.

Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster. When the sheet of paper is placed on the book, there is no air at all beneath it. For this reason, the two objects fall at the same speed. This force is called gravity.
