The angular acceleration of a body, moving along the circumference of a circle, is:
Angular acceleration lies along the axis of rotation.
The angular acceleration direction is given along angular velocity or opposite to angular velocity depending upon whether angular velocity magnitude is increasing or decreasing, and this direction remains along the axis of circular motion.
