Question

A sheet of paper falls slower than one that is crumpled into a ball.

• A. True
• B. False

Answer 1

The correct option is A True

Sheet crumpled into a ball has a small surface area as compared to the similar unfolded sheet. Therefore, unfolded sheets will experience more resistance due to air as compared to the sheet crumpled into a ball, in spite of the same force of gravity acting upon them. It is larger resistance of air which slows down the unfolded sheet, and therefore it falls slower as compared to the sheet crumpled into a ball.
