Conservation of Angular Momentum

This lecture covers the concept of conservation of angular momentum, explaining how the angular momentum of a system remains constant when no external forces are applied, and how it is affected by external forces in the case of rotation. Examples include the motion of the center of mass, the moment of inertia, and the modification of angular momentum. The instructor demonstrates how the angular momentum is preserved in various scenarios, such as circular motion and the use of a gyroscope. The lecture also discusses the implications of changes in moment of inertia and center of mass on the conservation of angular momentum.
