Momentanpol (m)

instantaneous centre of rotation (n)

The point where the relevant perpendiculars of two velocity vectors intersect is the instantaneous centre of rotation.

At this specific instant, the movement can be replaced by an infinitesimally small moment around the instantaneous centre of rotation.
