Linearity
Stability Analysis
Viewing videos requires an internet connection
Summary
This video introduces students to the notion of stability of equilibria. A temperature example is explored using an energy argument, and then the typical linear stability analysis framework is introduced. This framework is applied in detail to analyze a pendulum.
Learning Objectives
After watching this video students will be familiar with the framework of equilibrium and stability analysis.

It is highly recommended that the video is paused when prompted so that students are able to attempt the activities on their own and then check their solutions against the video.
During the video, students will:
- Identify whether two equilibria for a physical model are stable or unstable based on physical intuition.
- Find a linear approximation for the sine function near 0.
- Determine what happens to the solution when both eigenvalues for the eigenproblem near the equilibrium have negative real part.
- Determine what happens to the solution when at least one eigenvalue has positive real part.
- Determine what happens to the solution when the eigenvalues have zero real part.
- Work through the linear stability analysis framework for the top equilibrium of the pendulum.
