Worked Solution

Step 1: On Earth, air resistance opposes the motion of the light feather more than the heavy hammer. Step [2-9]: The Moon has no atmosphere, so there is no air resistance. Step [2-9]: Without air resistance, only gravity acts, pulling all objects at the same rate of acceleration.

Correct answer: There is no air resistance on the Moon.
