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 then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and clockwork motors in wind-up toys use elastic energy. In biological systems, molecular motors, like myosin in muscles, use chemical energy to create forces and eventually motion.
