Rotation, or spin, is the circular movement of an object around a central axis. A two-dimensional rotating object has only one possible central axis and can rotate in either a clockwise or counterclockwise direction. A three-dimensional object has an infinite number of possible central axes and rotational directions. If the … See more Mathematically, a rotation is a rigid body movement which, unlike a translation, keeps a point fixed.
