A Paper A experiences less air resistance.
B Paper A is heavier than Paper B.
C Gravity acts more strongly on Paper A.
D Paper B has less gravitational potential energy.

Worked Solution

Step 1: Both have the same weight pulling them down. Step [2-9]: Paper B has a larger surface area exposed to the air. Step [2-9]: This creates more air resistance (friction), slowing Paper B down more than Paper A.

Correct answer: Paper A experiences less air resistance.
