                  The variation of angular position q, of a point on a rotating rigid body, with time t is shown in Fig. Is the body rotating clockwise or anti-clockwise?                

Answer:

                  Slope of \[\theta -t\] graph tells the sense of rotation. If slope of \[\theta -t\] graph is negative, rotation is clockwise. If slope of \[\theta -t\] graph is positive, rotation is anticlockwise.
