Angular Acceleration is the rate of change of angular Velocity with respect to time. It is a vector quantity. It is denoted by $\alpha$. The Angular Acceleration Formula is given by:
Where, $\omega$ is the angular velocity and t is the time taken.
Angular Velocity $\omega$ is given by
Where, $\theta$ is the angle rotated and t is the time taken.
Thus the angular acceleration $\alpha$ is given by
These formulas are helpful in solving problems based on angular acceleration.
