With a rubber band, when is the potential energy stored in the rubber band and when is the kinetic energy released?
What is Potential energy is stored when the rubber band is stretched out of shape, and kinetic energy is released when the rubber band goes back to its original shape (or flies through the air).

True or False: When we were bouncing the basketballs, the potential energy of the basketballs were both gravitational potential energy and elastic potential energy and this energy was converted into kinetic energy.
What is True because the basketball was off the ground and when the ball hit the ground it was stretched by the floor and then it went back to it's original shape.
