Stable equilibrium is a location at which a small displacement results in a force opposite the direction of the displacement, accelerating the object back toward the equilibrium position. Stable equilibrium positions exist where the potential energy as a function of position has a local minimum. Unstable equilibrium is a location at which a small displacement results in a force in the same direction as the displacement, accelerating the object away from the equilibrium position. Unstable equilibrium positions exist where the potential energy as a function of position has a local maximum.Sections:00:00 - Force and potential energy01:45 - Graphs of potential energy vs. position02:44 - Determining force magnitude06:04 - Determining force direction08:04 - Stable and unstable equilibrium points11:35 - Intuition behind potential energy graphs------------------Khan Academy is a nonprofit organization with the mission of providing a free, world-class education for anyone, anywhere.
