Electrical energy can be converted back into kinetic energy in electric motors: this happens with the windscreen wipers and the starter motor. Electrical energy is converted into light energy in the headlights. In fact the only kind of energy which you will not find in your car is nuclear energy.
Discuss the idea that as mechanical energy was converted into electrical energy at the power plant, electric energy is now to be converted back to mechanical energy by a motor. Make some simple drawings of how magnets work in the operation of a motor. Discuss the use of the motor in industry and how other applications of the motor might work.
