Mechanical Energy Conservation

This lecture covers the concept of mechanical energy conservation in physics, focusing on the relationship between potential and kinetic energy. It discusses the transformation of linear equations into quadratic equations, the laws of motion, and the conservation of energy. The instructor explains how to find the position as a function of time and energy, the return force of a spring, and the harmonic oscillator. Additionally, it explores the concept of conservative forces, potential energy in rectilinear motion, and the conservation of mechanical energy. The lecture concludes with examples illustrating the application of these principles.
