RANGEOFMOTION
Range of motion
Range of motion, is the distance that a movable object may normally travel while properly attached to another. It is also called range of travel, particularly when talking about mechanical devices and in mechanical engineering fields. For example, a volume knob may have a 300° range of travel from the "off" or muted position at lower left, going clockwise to its maximum-loudness position at lower right.The above text is a snippet from Wikipedia: Range of motion
