Answer:
The centre of gravity (COG) of the human body is a hypothetical point around which the force of gravity appears to act. It is a point at which the combined mass of the body appears to be concentrated.
The centre of gravity (COG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human's centre of gravity can change as he takes on different positions, but in many other objects, it's a fixed location.
