Potential energy diagram

Definition

A potential energy diagram is a graphical representation that shows the potential energy of a system as a function of its configuration or position. It is used to analyze the stability and equilibrium points of the system.

5 Must Know Facts For Your Next Test

1. Potential energy diagrams can illustrate both stable and unstable equilibrium points.
2. The slope of the potential energy curve at any point is related to the force acting on the system: $F = -\frac{dU}{dx}$.
3. Local minima on the diagram represent stable equilibrium positions, whereas local maxima represent unstable equilibrium positions.
4. Potential energy diagrams are useful for visualizing transitions between different states in conservative systems.
5. The area under a force vs. position graph can be interpreted using the potential energy diagram.
