Which of the following is true about angular acceleration in circular motion?
(Select all that apply.)
1. None of these are correct.
2. It has units of s-2.
3. It increases the angular velocity if both angular velocity and angular acceleration are in the same direction.
4. It is equal in magnitude to the tangential acceleration divided by the radius.
Thank You very much for your help!!!
