Vedclass · Answer

(C) Angular acceleration $(\alpha)$ is defined as the rate of change of angular velocity $(\omega)$ with respect to time $(t)$.Mathematically,$\alpha = \frac{d\omega}{dt}$.The $SI$ unit of angular velocity $(\omega)$ is radians per second $(rad\,s^{-1})$.Therefore,the $SI$ unit of angular acceleration is $\frac{rad\,s^{-1}}{s} = rad\,s^{-2}$.Thus,the correct option is $C$.

The unit of angular acceleration in the $SI$ system is
