Dynamics: Simple Pendulum

This lecture focuses on the dynamics of a simple pendulum, describing its motion along a circular trajectory and the forces acting on it. The instructor explains the relationship between the angle and the position of the mass, introduces the concept of equivalent vectors, and discusses the acceleration of the mass. The lecture also covers the application of these principles to circular movements and compares the motion of a pendulum with that of a rotating ping pong ball. By analyzing the synchronization of these movements, the lecture highlights the similarities between seemingly different motions.
