angular acceleration is the rate of change of the \[angular velocity\] with time, or the second derivative of the \[angular position\] with respect to time. It's the angular analogue to linear \[acceleration\] . Like the angular velocity, it is a vector quantity, having both direction and magnitude. It is usually represented by the small Greek letter alpha, α.
