A brown line has a label Ground beneath it. Above it are a flat piece of paper on the left and a crumpled piece of paper on the right. Jamal wanted only to test the effect of the free fall and so he put his system in a vacuum to prevent air resistance. In free fall, will the crumpled or flat paper reach the ground first?

The crumpled paper will reach the ground first.
The flat paper will reach the ground first.
Both papers will reach the ground at the same time.
It is hard to tell which would reach the ground first without experimentation.
