Question:

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

Answer:

The area of a sheet of paper is greater than that of a ball made by twisting or crumpling the same sheet, so the opposing force exerted by the wind on the sheet of paper is greater than that of the ball. Hence the sheet of paper falls slower than the ball made by crumpling the same type of the paper.
