Final answer:
The center of gravity is the point where both body mass and weight are equally distributed. It is identical to the center of mass, which is the point about which the system's mass is evenly distributed.
Step-by-step explanation:
The point at which both body mass and weight are equally distributed is called the center of gravity. It is the point where the total weight of the body is assumed to be concentrated. In practical situations, the center of gravity is identical to the center of mass, which is the point about which the system's mass is evenly distributed. For example, in a rigid object, this center of mass is the point where the object will stay balanced even if only supported at this point.
