Question

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

Answer 1

Answer:

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:

A sheet of paper has a larger area. Due to its large area, when a sheet of paper is dropped from a height, it experiences more resistance from air, its speed decreases and it falls at a slower rate. On the other hand, a sheet of paper crumpled into a ball has a smaller area. Due to its smaller area, when a ball made from crumpled sheet of paper is dropped from a height, it experiences less resistance from air, its speed increases and it falls at a faster rate.
