I got the answer but I need help explaining them using laws of physics and connecting that with the specific circumstances of the questions.

12. A feather and a hammer are dropped from the same height at the same time on the moon. They land at the same time. What does this show? (A) The acceleration due to gravity on the Moon is less than the acceleration due to gravity on the Earth (B) The gravitational force from the Moon on heavier objects (the hammer) is equal to the gravitational force on lighter objects (the feather) (C) A hammer and feather have less mass on the Moon than on Earth (D) In the absence of air resistance all bodies at a given location fall with the same acceleration\f\f
