The concept of tangential acceleration is used to measure the change in the tangential velocity of a point with a specific radius with the change in time. The linear and tangential accelerations are the same but in the tangential direction, which leads to the circular motion.

What is the rule of tangential acceleration?

It always acts perpendicular to the centripetal acceleration of a rotating object. It is equal to the angular acceleration α, times the radius of the rotation. tangential acceleration = (radius of the rotation)(angular acceleration) a_tan = rα a_tan = tangential acceleration.

What is the difference between normal acceleration and tangential acceleration?

The tangential acceleration is a measure of the rate of change in the magnitude of the velocity vector, i.e. speed, and the normal acceleration are a measure of the rate of change of the direction of the velocity vector.
