Rotations in Two Dimensions

This lecture covers the concept of rotations in two dimensions, including the vector product, moment of a force, statics, and the theorem of angular momentum. It also explores the cases of a point mass, a system of material points, and a rigid body. The lecture delves into the application of Newton's laws to rotational motion, emphasizing the balance of forces and moments. Additionally, it discusses the behavior of solid objects rotating around an axis, highlighting the importance of moment of inertia in determining the ease of rotation.
