because it is more lighter than the crumpled one. and its density is much lighter.
-- If they're dropped in a place where there is air, then that could be accomplished byeither dropping the paper some time before the book, or from a height much lower thanthe height from which the book is dropped.-- If they're dropped in a place where there is noair, then all you have to do is dropthem at the same time from the same height. Without air, they fall together, and reachthe bottom at the same time.
Because when the sheet of paper is flat, it acts like a parachute, and collects much more air resistance. The balled-up piece of paper has much less surface area, so can collect much less air resistance, making it fall faster.
Paper falls more slowly then a stone because paper weighs less then stones.
The paper has more surface area and therefore more air resistance than the marble does. If you wad up the sheet of paper in a tight ball, you'll see very little difference in the falling speed.
it would be 9.8 meter per second. anything that isn't subject to air resistance(like paper) will fall at this rate for this is the acceleration of gravity,
Between rock and paper, paper is lighter. However if dropped from same height they do fall at the same speed.

The height of a piece of paper folded in half once is half of its original height.
Because of its mass.
It was a factory who had already made normal paper, but dropped something in it and turned colorful. Since then, they've made colored paper.
it would be 9.8 meter per second. anything that isn't subject to air resistance(like paper) will fall at this rate for this is the acceleration of gravity,
Assuming a standard sheet of paper is 0.1mm thick, the height of a million sheets of paper stacked on top of each other would be 100 meters (328 feet).
148mm × 210mm
The width and height of ISO A4 paper is 210 × 297 mm.
