Try to count all the engines and motors that you and your family operate. Cars and lawn mowers may be the most obvious, but some people also use snow blowers, chain saws, and motorcycles. We have become dependent on engines and motors. They produce the power we need to carry people and goods. It would be difficult to operate other technologies if we couldn't generate power for transportation. Without power for transportation, how would you get to school or visit far-away relatives or friends. Do you know the difference between engines and motors? Both convert energy into motion that enables us to do work. Motors usually run on electric energy, and the motion they produce is rotary (circular) motion. Engines use heat energy to produce motion. People often use the terms motors and engines interchangeably. You can say, for example, that a car is powered by an engine or a motor. However, there are no electric engines, only electric motors.
