Question

A tennis ball and a bowling ball are dropped from the same height at the same time on the moon. Based on what you have read about Galileo’s experiments, describe the behavior of the balls.

Answer 1

They will hit the ground at the same time.

Answer 2

Answer:

They will hit the bottom at the same time.

Explanation:

The moon has no atmosphere and hence, there is no air drag. In the absence of air drag, when a tennis ball  and a bowling ball are dropped from the same height at the same time, they would hit the surface of the moon at the same time. This can be explained on the basis of the results of Galileo's experiment.

The time of descent is independent of mass of the balls. The balls would freely fall under action of gravity only that is both the ball would have same acceleration (due to gravity).
