Ship stability diagram showing centre of gravity (G), centre of buoyancy (B), and metacentre (M) with ship upright and heeled over to one side. As long as the load of a ship remains stable, G is fixed (relative to the ship). For small angles, M can also be considered to be fixed, while B moves as the ship heels.
Diagram of an educational toy that balances on a point: the center of mass (C) settles below its support (P) A body's center of gravity is the point around which the resultant torque due to gravity forces vanishes. [13] Where a gravity field can be considered to be uniform, the mass-center and the center-of-gravity will be the same.

The center of gravity (CG) of an aircraft is the point over which the aircraft would balance. [1] Its position is calculated after supporting the aircraft on at least two sets of weighing scales or load cells and noting the weight shown on each set of scales or load cells. The center of gravity affects the stability of the aircraft.
Center of gravity (COG) is a military concept referring to the primary source of strength, balance, or stability necessary for a force to maintain combat operations. Centers of gravity can be physical, moral, or both, and exist for all belligerents at all tactical , strategic , and operational levels of war simultaneously. [ 1 ]
True wind (V T) is the same everywhere in the diagram, whereas boat velocity (V B) and apparent wind (V A) vary with point of sail. Forces on sails result from movement of air that interacts with sails and gives them motive power for sailing craft, including sailing ships , sailboats , windsurfers , ice boats , and sail-powered land vehicles .
The following is a list of centroids of various two-dimensional and three-dimensional objects. The centroid of an object in -dimensional space is the intersection of all hyperplanes that divide into two parts of equal moment about the hyperplane.
The center of gravity seeks to explain this effect. Formally, a center of gravity is an application point of the resultant gravitational force on the body. Such a point may not exist, and if it exists, it is not unique. One can further define a unique center of gravity by approximating the field as either parallel or spherically symmetric.
