The term 'REVOLVE OR ROTATE' can be summarized by the four-letter word 'TURN'. To TURN is to move in a circular motion around an axis, or to cause something to do so. It is often used to describe the movement of objects in space, such as planets and stars. It can also be used to describe the movement of objects on a smaller scale, such as a wheel or a top. In either case, the object is moving in a circular motion, which is what the term 'REVOLVE OR ROTATE' describes.
