  • #2
    A simple pendulum is a point mass suspended by a light thread from a fixed point. The particle is displaced towards one side and then released. It makes small oscillations. Is the motion of such a simple pendulum a pure rotation? If yes, where is the axis of rotation?
    Ans : Yes, it is an example of pure rotation.
    The axis of rotation passes through the pivot of the pendulum, perpendicular to the plane containing the pendulum.
