stable equilibriumA body at rest is in stable equilibrium if, when slightly displaced, it tends to return to its original position of equilibrium. If the displacement tends to increase, the body is said to be in unstable equilibrium. Positions of stable equilibrium are positions of minimum potential energy; those of unstable equilibrium are of maximum potential energy.
