Engine

An engine or motor is a machine designed to convert one form of energy into mechanical energy (see Motion (physics)).

Description

Heat engines, including internal combustion engines and external combustion engines (such as steam 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

Clockwork motors in wind-up toys—use elastic energy.

In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.
