Assertion : In rolling, all points of a rigid body have the same linear velocity.
Reason : The rotational motion does not affect the linear velocity.

A : In purc rolling motion all the points of a rigid body have same linear velocity. R : Rolling motion is not possible on smooth surface.

What is analogues to mass of linear velocity in rotational motion?

In rotational motion of a rigid body, all particles move with

Linear velocity of particles of rigid body in rotational motion is same.

Consider the following two statements A and B and identify the correct choice A) When a rigid body is rotating about its own axis, at a given instant all particles of body posses same angular velocity. B) When a rigid body is rotating about its own axis, the linear velocity of a particle is directly proportional to its perpendicular distance from axis
