Suppose Galileo dropped a lead ball (100 kilograms) and a glass ball (1 kilogram) from the Leaning Tower of Pisa. Which one hit the ground first? (Assume that there is no air resistance.)
Assuming there is no air resistance and the experiment took pace in a controlled environment, both the lead ball and the glass ball would hit the ground at the same time.
IF there is no air resistance, then he could drop a feather, a piece of Kleenex, a school bus, and a battleship. If he dropped them all at the same time from the same height, they would all hit the ground at the same time.
