Kinetic energy, also known as the energy of motion, is all around us in different forms. Without it, there would be no light, heat, sound, or movement. Only when the other major type of energy, potential energy, converts to kinetic energy are we able to see, hear, and move about. Kinetic energy even works at the molecular level. Vibrating molecules produce heat, and subatomic particles called electrons can flow together to create electricity. From the basic movement of atoms producing heat to a car screeching to a stop, kinetic energy affects our everyday lives.
