If a feather and a hammer are dropped at the same time on the moon, where there is no atmosphere, which one will hit the ground first?
neither, there is no gravity on the moon.
hammer because it has more mass
feather because it has less mass
both will hit at the same time, there is no wind resistance

A student drops a bowling ball and an apple from a third-story window. Both objects hit the ground at the same time. From the experiment, the student should conclude that
the apple weighs more than the bowling ball
more air friction is acting on the apple than on the bowling ball
gravity pulls on both objects, causing them to fall at the same time.
