What will fall faster- a plain piece of paper of a piece of paper crumpled into a ball? Explain why.

A plain piece of paper and a crumpled piece of paper will fall at the same rate. Both objects have the same mass and are affected by the same gravitational force. The shape or size of the object does not impact the speed at which it falls in a vacuum.

However, in a real-world scenario with air resistance, a crumpled piece of paper may fall slightly slower than a plain piece of paper due to its increased surface area. The increased surface area of the crumpled paper results in more air resistance, which can slow down its descent.
