Classification of Conservative Systems and Turning Points, Study notes of Mechanics
The concepts of conservative systems, equilibrium points, stable and unstable points, and turning points in the context of physics. The lecture notes discuss the expansion of potential energy functions in series, the determination of equilibrium points, and the classification of stable and unstable points. Additionally, the document explores turning points, which are the places where particles change direction based on their energy levels.

Draw a parabola on the board and discuss motion
Classification of points: Expand U(x) in a series (for simplicity let's say around x= If the first term is zero, the we have an equilibrium point. (Pick out where they are on the graph.) Stable vs. Unstable
