Angular velocity: the velocity with which an object is moving around a fixed axis of rotation (this is different from ordinary velocity!); different points on a rotating rigid body move different distances in a given time interval, depending on how far the point lies from the axis; but, because the body is rigid, all points rotate through the same angle in the same time; at any instant, every part of a rotating body has the same angular velocity (rad/s); linear velocity = r x alpha
