3. When an object moves, its energy changes form. When a ball bounces, it has changing amounts of potential energy and kinetic energy. Eventually, however, the ball will stop bouncing. Why does the ball stop bouncing?
A. The ball’s energy gets used up each time it bounces.
B. The mass of the ball is too small to allow it to continue its own motion.
C. The ball’s energy gets transferred to other energy types like heat and sound that don’t help it bounce.
D. The pull of gravity is stronger than the energy in the ball, which makes the ball slow down to a stop.
