Most materials are unstable or metastable. A material is in a metastable state if its energy is at a local minimum, but not the lowest energy state. A corrie lake is a metastable location of water. Water in the lake attains its lowest energy when it reaches the sea.

A system is said to be in stable equilibrium if, when displaced from equilibrium, it experiences a net force or torque in a direction opposite to the direction of the displacement. For example, a marble at the bottom of a bowl will experience a restoring force when displaced from its equilibrium position.
