Which will experience more air resistance: a flat sheet of paper or a piece of paper crumpled up into a ball? Why?

Answer 1

A piece of paper crumpled up into a ball will experience more air resistance compared to a flat sheet of paper. This is because the crumpled ball shape increases the surface area of the paper that is exposed to the air flow. As a result, there is more surface area for the air to exert resistance against, causing more drag on the crumpled paper ball as it moves through the air. In contrast, a flat sheet of paper has less surface area exposed to the air, resulting in less air resistance.
