Question

why will a sheet of paper for slower than one that is crumpled into a ball​

Answer 1

Answer:

Its because of surface force acting on the body

Explanation:

CASE I

where paper is plain surface force acting on it is huge compared to the rolled up paper so, It's slows down fast

CASE 2

here paper is crumpled as mentioned then due to the pressure acting is more in this one

P= F/A

hence I declare that as area decreases pressure increase

Answer 2

Answer

A sheet of paper has a large surface area. So it experiences a greater air resistance while falling than a crumpled ball. Thus it falls slower.
