Dynamics: Momentum and Newton's Laws

This lecture covers the dynamics of objects, focusing on momentum and Newton's laws. It explains how forces affect the motion of objects, using examples like a symmetric dumbbell. The instructor discusses the concept of momentum and how it relates to the total mass of an object. Newton's second law is presented, showing how external forces impact an object's center of mass. The lecture concludes with an analysis of the trajectory of the center of mass, illustrating how forces like gravity influence the motion of objects.
