A golf ball and a Ping-Pong ball are dropped in a vacuum chamber. When they have fallen halfway to the bottom, how do their speeds compare? Their kinetic energies? Their potential energies?A golf ball and a Ping-Pong ball are dropped in a vacuum chamber. When they have fallen halfway to the bottom?Their speed will be the same their kinetic and potential energy will be according to their mass.
