Question

How is mechanical energy generated in a car?

Answer 1

in engine it is generated by driving and drive wheel (they are not car wheel they are toothed wheel in image ) which is further attached to shaft which move wheel

Answer 2

Objects have mechanical energy if they are in motion and/or if they are at some position relative to a zero potential energy position (for example, a brick held at a vertical position above the ground or zero height position). A moving carpossesses mechanical energydue to its motion (kinetic energy).
