If the gravity acting on every segments of the object is same, then the center of gravity and center of mass for that object remains the same. Considering the human body, the force of gravity acting on various segments depends on the position of the body, distance from the ground and the movement taking place.he centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is point at which the combined mass of the body appears to be concentrated.
