What is energy?
... Hearing Sounds The figure shows how electrical energy is transformed into other kinds of energy when you listen to a radio. A loudspeaker in the radio changes electrical energy into sound waves. The sound waves travel to your ear. This is energy in motion. The energy carried by the sound waves makes ...
