Derivation of Pendulum equations method 1

The video tutorial explains how to calculate the equation of motion for a pendulum by making several assumptions, such as the rope being massless and frictionless. It uses energy methods to derive the equation, focusing on kinetic and potential energy. The tutorial simplifies the equation and differentiates it to find solutions, ultimately providing a comprehensive understanding of pendulum motion.
