CAR ENGINE

An engine or motor is a machine designed to convert one form of energy into mechanical energy. Heat engines burn a fuel to create heat, which is then used to create a force. Electric motors convert electrical energy into mechanical motion; pneumatic motorsuse compressed air and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosins inmuscles, use chemical energy to create forces and eventually motion.
