Question

11. Why will a sheet of paper fall slower than one that is crumpled
into a ball?​

Answer 1

Answer:

HERE'S YOUR ANSWER DEAR

Explanation:

A sheet of paper falls slower then the one crumpled into a ball because the surface area of the ball is much lower than that of the sheet. Thus the upward force exerted by air on the sheet is much as compared to the one exerted on the ball. Hence the sheet falls slower.

Answer 2

Answer:

This is because of the difference in surface areas of a sheet of paper and a paper crumpled into a ball. A sheet of paper has larger surface area as compared to a crumpled paper. As a result of this, a sheet of paper experiences more air resistance than a crumpled ball of paper.  

However, in the absence of air resistance, that is in vacuum, both sheet of paper and crumpled ball of paper falls with the same speed.
