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 flat sheet of paper will experience more air resistance than a piece of paper crumpled up into a ball. This is because the flat sheet of paper has a larger surface area that comes into contact with the air, creating more friction and resistance as it moves through the air. On the other hand, a piece of paper crumpled up into a ball has a smaller surface area, resulting in less air resistance as it moves through the air.
