Question

Engine of a car exerts which force?

Answer 1

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.
