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?
Yes, this is an example of pure rotation.

The axis of rotation is in the perpendicular direction of the plane of oscillation through the fixed point.
