Vedclass · Answer

(C) In pure translational motion,at any instant of time,all particles of the body have the same velocity. However,in rolling motion (which is a combination of translational and rotational motion),the velocity of any point on the body is the vector sum of its translational velocity and its rotational velocity. Since the rotational velocity depends on the distance of the point from the axis of rotation,different points on the body have different velocities at any given instant. Therefore,the magnitudes of the velocities of points $P_1$ and $P_2$ are not equal,i.e.,$\left| {{{\vec v}_1}} ight| 
e \left| {{{\vec v}_2}} ight|$.

For a rolling body,the velocities of points $P_1$ and $P_2$ are ${\vec v_1}$ and ${\vec v_2}$,respectively. Which of the following is correct?
