4. Angular Acceleration
The rate of change of angular velocity is defined as angular acceleration. If Δω be change in angular velocity in time Δt, then angular acceleration

(i) It is a vector quantity
(ii) Its direction is that of change in angular velocity
(iii) Unit : rad/sec2
(iv) Dimension : M0L0T–2
