Centre of gravity - the point within something at which gravity can be considered to act; in uniform gravity it is equal to the center of mass.

Centre of gravity, in physics, imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. The concept is sometimes useful in designing static structures (e.g., buildings and bridges) or in predicting the behaviour of a moving body when it is acted on by gravity.

In a uniform gravitational field the centre of gravity is identical to the centre of mass, a term preferred by physicists. The two do not always coincide, however. For example, the Moons centre of mass is very close to its geometric centre (it is not exact because the Moon is not a perfect uniform sphere), but its centre of gravity is slightly displaced toward the Earth because of the stronger gravitational force on the Moons near side.

The location of a bodys centre of gravity may coincide with the geometric centre of the body, especially in a symmetrically shaped object composed of homogeneous material. An asymmetrical object compos ...more

This is one of those concepts that's easy to get your brain around but very hard to define.
It is a point that is usually -- but not always -- located within a body (that is, an object) upon which gravity can be thought of as acting. Think of this way: imagine that the entire mass of an object was compressed to a single point in space. That single point would have potential energy (given by the formula Ep = mgh), which would be the potential energy of the uncompressed object. You can think of gravity -- and the potential energy it creates -- as acting on that single point.
Center of gravity is also known as the center of mass under a uniform gravitational field.
