causes it to have less air resistance.

Detailed explanation-1: -A crumpled paper ball has a reduced area as compared to a sheet of paper which has a larger surface area. So, the sheet of paper will face a lot of air resistance when the sheet of paper is dropped from a height as its area is large.
Detailed explanation-2: -It all comes down to form. When the paper is smooth, it exposes a large surface to the air beneath it which slows its descent. Once it is crumpled, the surface which comes in contact with the air is much smaller, allowing it to fall much faster.
Detailed explanation-3: -When a sheet of paper is crumbled into a ball, its surface area decreases. Hence, it experiences less air resistance to its motion and it falls faster than the sheet of paper.
Detailed explanation-4: -The crumpled ball has smaller surface area as compared to sheet of paper. The air resistance on sheet of paper when dropped from a height is larger than air resistance on crumpled paper ball. This air resistance decreases the speed of the sheet of paper.
Detailed explanation-5: -The crumbled papper will reach the ground first. because the crumbled papper have less surface area that’s why it will affect less air friction. the plane papper have large surface area then it posses high air friction.
