Dynamics: Newton's Laws

This lecture covers the third law of Newton, which states that for every action, there is an equal and opposite reaction, as well as the second law, which explains how external forces affect the total momentum of an object. Through experiments on momentum conservation during collisions, the instructor demonstrates the concepts of elastic and inelastic collisions, emphasizing the conservation of momentum and kinetic energy. The lecture also explores collisions between balls on a shield, illustrating the conservation of momentum and kinetic energy. Various examples and mathematical formulations are provided to deepen the understanding of these fundamental laws of dynamics.
