Rotation in Two Dimensions

This lecture covers the concept of rotation in two dimensions, focusing on the moment of inertia and angular acceleration. Examples include a wire wound around a vertically fixed wheel and a slider driven by a counterweight on a horizontal air track. The lecture also explores the acceleration differences between a solid disk and a ring, as well as the dynamics of a physical pendulum. The importance of the distribution of mass and moment of inertia in achieving stability, as demonstrated by the use of a long pole by a tightrope walker, is also discussed.
