Mechanics: Potential Energy and Oscillations

This lecture covers the concept of potential energy in rectilinear motion, focusing on different position ranges and equilibrium points. It also discusses examples like bungee jumping and the calculation of maximum velocity. The instructor explains the relationship between mechanical energy, gravity, and conservative forces, emphasizing the calculation of maximum velocity and the impact of air resistance. The lecture concludes with a detailed analysis of equilibrium points and small oscillations in harmonic motion.
