STABILITY is one's degree of EQUILIBRIUM.

STABILITY is inversely proportional to the distance of the body's CENTER OF GRAVITY above the base (the closer one's Center of Gravity is to the base of support).

The CENTER of GRAVITY of an object must fall within the boundaries of its base of support for EQUILIBRIUM to exist.

STABILITY is directly proportional to the AREA of the base upon which a body rests. Increase in area at the base increases stability.

STABILITY is directly proportional to one's bodyweight. All other factors being equal, a heavier person is more stable than a lighter person.
