FACTS

centre of gravity is the point in a body around which the resultant torque due to gravity forces vanishes.

Near the surface of the earth, where the gravity acts downward as a parallel force field, the center of gravity and the cente r of mass of an

arbitrary body are the same.

CONCEPTS

centre of gravity- The center of mass is the unique point at the center of a distribution of mass in space that has the property that the weighted position vectors

relative to this point sum to zero. In analogy to statistics, the center of mass is the mean location of a distribution of mass in space.
