The weight of a differential volume element dV for a body occupying the region is given by DW = dV, where is the weight density (weight per unit volume). The most common example of a distributed force is the weight of a body. In other words we can say that “the location where a body's total weight is concentrated, so that if supported at this location, the body would maintain equilibrium in any configuration.” Centre of Gravity Formula A body can only have one centre of gravity in any given position.” It is symbolized or indicated by the letters C.G. “The point through which a body's entire weight acts is known as the centre of gravity. Thus, it should not be surprising that engineers use the phrases centre of mass and centre of gravity interchangeably. Differences only appear in situations when the gravitational field is not uniform. However, we find that the centres of mass and gravity coincide in most situations since weight and mass only differ by a constant factor (assuming that the gravitational field is uniform). In dynamics, the centre of mass of a body, a characteristic of how the body's mass is distributed inside it and the location through which the resulting inertia force acts, is an important term. The distribution of weight within the body consequently determines the centre of gravity. The weight of a body, which is the result of gravitational forces acting on it, acts through a location known as the body's centre of gravity.
