The center of gravity (CG) of an object is the point at which weight is evenly dispersed and all sides are in balance. A human's center of gravity can change as he takes on different positions, but in many other objects, it's a fixed location.

The center of gravity of an object is calculated by taking the sum of its moments divided by the overall weight of the object. The moment is the product of the weight and its location as measured from a set point called the origin.

⇒ Centre in of gravity is a point where whole weight of a body is supposed to be concentrated .

⇒ It varies with our positions , when we stand COG is at our Belly button , when we take different positions it varies .

⇒ Also you can say it a balancing point
