The talk is about the section of Feynman's Lessons in Physics, Volume I, Chapter 18, which deals with rotation in two dimensions. He begins by explaining the concept of the center of mass and how it moves with constant velocity in the absence of external forces. It then introduces the concept of rigid body and the kinematics of rotation, defining quantities such as angle, angular velocity and angular acceleration. The concept of torque is introduced and various ways of calculating it are explored. Finally, the concept of angular momentum, which is a quantity analogous to linear momentum, is introduced and the conservation theorem of angular momentum for a system of particles is established. This theorem is related to the moment of inertia of a rigid body, and it is explained how the moment of inertia can vary, and how this affects the angular velocity of an object. • https://www.feynmanlectures.caltech.e...
