Infer how potential energy is changed into kinetic energy and back into potential energy.?
flyball is a sport for dogs. After leaping over a four hurdles, a dog jumps on a spring-loaded box taht shoots out a tennis ball. The ball flies through the air, adnt eh dog must catch it..
when the ball is in the box it has potential energy, then when it flies out it has kinetic energy. Once the dog catches it and it is still again it regains potential energy
