Constrained Motion: Sphonic Coordinates

This lecture covers the concept of constrained motion in physics, focusing on the use of sphonic coordinates to describe the finalie of a system under various constraints. The instructor, Stefan Nikolic, explains the forces involved, such as mg and liecon, and introduces the potential V(x, y, z) to analyze the system's behavior. The lecture delves into the gravitational contribution, the introduction of potential V(x, y, z), and the stability of equilibrium points. It also discusses harmonic oscillators and stability criteria in different frames of reference, providing numerical examples and theoretical explanations.
