Simple Pendulum Dynamics

This lecture covers the dynamics of a simple pendulum, exploring the forces involved, the equations of motion, and the impact of initial conditions on the period of the pendulum. The instructor explains the concept of moment of force and how it affects the rotation of the pendulum, emphasizing the importance of understanding the tension in the pendulum's string. The lecture also delves into the mathematical analysis of the pendulum's motion, highlighting the non-linearity of the equations and the relationship between the pendulum's length and its harmonic motion. The instructor demonstrates how to derive the differential equations governing the pendulum's motion and discusses the implications of different initial conditions on the tension in the string.
