Question

When a piece of paper and a coin are dropped from the same height simultaneously. The coin reaches the ground first and paper takes some times in reaching to the ground. It we crumple up the piece of paper in the form of a ball and let the two drop from the same height again they reach the ground almost at the same time. Explain the science behind this activity.

Answer 1

All this cause of weight e.g. no :- 1. the paper has no weight so he drooped slowly and coin has weight . e.g no:- 2 u drooped tow balls they have weight so 2balls fall together .

Answer 2

first case,the weight of the coin in comparatively more than the piece of paper also in case of the paper the surface area is more so downward pressure is less
second case,as the paper is crumbled the surface area gets redused as a result the downward pressure increases
Due to the aforesaid reasons the crumbled paper and the coin reach the ground almost at the same time....
