Answer: When you let go of that ball and let it fall, the potential energy converts into kinetic energy. If you pt a toy car at the top of a hill And let go it starts to move witch converts it into kinetic energy. If you raise your hand and start to wave at someone, kinetic energy. Spin a chair while it spinning it has kinetic energy. Close a door while it closes it also has kinetic energy.
Explanation: When you let go of that ball and let it fall, the potential energy converts into kinetic energy, or the energy associated with motion. There are five types of kinetic energy: radiant, thermal, sound, electrical and mechanical.
