The variation of angular position $\theta$ of a point on a rotating rigid body with time $t$ is shown in the figure. Is the body rotating clockwise or anti-clockwise?

(N/A) The angular velocity $\omega$ of a rotating body is defined as the rate of change of its angular position $\theta$ with respect to time $t$,given by $\omega = \frac{d\theta}{dt}$.
In the given graph,the slope of the $\theta-t$ plot represents the angular velocity $\omega$.
The slope of the line is positive,which means $\frac{d\theta}{dt} > 0$.
By convention,a positive rate of change of angular position (increasing $\theta$) corresponds to an anti-clockwise rotation.
Therefore,the body is rotating in an anti-clockwise direction.
