motor

A motor runs your car, whizzes the blender and gets your golf cart going: it's simply a machine that converts energy into motion.

Coming to us from a Latin word that means "to move," motor is certainly connected to the world of motion. Without the innovation of Ford motors, most of America wouldn't be able to get anywhere today. These days the motor is undergoing some serious revisions, as engineers look for a way to power things with less gasoline and more sunshine.
