The centre of mass (or centre of gravity) of a set of points. In the dynamics of a rigid body, the forces acting may be resolved into those displacing the body as a whole, which may be considered as acting at the centre of mass, and rotational forces. For example, a rigid body moves under the influence of gravity as if its mass were concentrated at the barycentre. Geometrically, the barycentre is at the centroid of the body.
