Lecture
This lecture covers the analysis of the motion of a simple pendulum, focusing on the concepts of angular displacement, velocity, and acceleration. It explains how to calculate the angular displacement and the velocity of the pendulum at different instants, emphasizing the relationship between displacement and time. The lecture also discusses the concept of average velocity and the importance of precision in measuring the motion of the pendulum. Furthermore, it explores the notion of angular velocity and its significance in determining the speed of the pendulum at various time intervals.
