Center of Mass

In physics, the center of mass or barycenter of a body is a point in space where, for the purpose of various calculations, the entire mass of a body is concentrated. The center of gravity is a related point where the gravitational weight of a body acts as if it were concentrated. In a uniform gravitational field this point is found at the center of mass, and In common usage, the two points are considered the same. In a non-uniform field, the center of mass no longer serves as the exact center of gravity, so physicists often distinguish the center of gravity as a separate concept. Read more on – Wikipedia
