How potential energy graphs reveal the stability of a system
In short: Learn to identify stable and unstable equilibrium by analyzing the peaks and valleys of potential energy graphs. This video explains how forces react when an object is displaced from its resting position.
The video explores the relationship between position and potential energy. It explains that stable equilibrium occurs at a local minimum, where a small movement triggers a force that pushes the object back toward its original spot. Conversely, unstable equilibrium exists at a local maximum, where any displacement creates a force that accelerates the object further away from the equilibrium point.
