The centre of gravity (CG) of an object is the point at which the entire weight of the object can be considered to be concentrated. It is the point where the object would balance perfectly if supported. It's essentially the average position of the object's mass. For a uniform object, the CG is at the geometric centre. For non-uniform objects, it can be calculated using integrals or approximated.
