Question

An engine or motor is a machine designed to convert one form of energy into mechanical energy.[1][2] heat engines burn a fuel to create heat which is then used to do work. 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 myosins in muscles, use chemical energy to create forces and eventually motion. in modern usage, the term engine typically describes devices, like steam engines and internal combustion engines, that burn or otherwise consume fuel to perform mechanical work by exerting a torque or linear force (usually in the form of thrust). devices converting heat energy into motion are commonly referred to simply as engines.[3] examples of engines which exert a torque include the familiar automobile gasoline and diesel engines, as well as turbo shafts. examples of engines which produce thrust include turbofans and rockets.
