The change in the central angle with respect to time as an object moves along a circular path (Lesson 7 7)
The rate of rotation of a particle about the axis of rotation, with magnitude equal to the time rate of angular displacement of any point of the body Angular velocity is a vector oriented in accordance with a right-hand rotation (i e , when the fingers of the right hand are curved in the sense of rotation, the thumb points in the direction of the angular velocity vector)
