General Physics: Mechanics

This lecture introduces a new chapter on the phenomenon of gravitation, focusing on central forces and angular momentum. The instructor explains the implications of Newton's laws, emphasizing the conservation of momentum and the characteristics of circular motion. The concept of angular momentum is introduced, highlighting its importance in simplifying the solution to gravitational problems. The lecture also covers the conservation of angular momentum and its role in describing motion in a central force field. The instructor demonstrates how the conservation of angular momentum leads to a solution that depends only on the radial distance, providing a general solution to central force problems.
