General Physics: Mechanics

This lecture covers the concept of moment of inertia and kinetic energy in solids, focusing on theorems related to rotational motion. The instructor explains the calculations for the center of mass of various objects, including squares and discs, and demonstrates how to determine the moment of inertia for different shapes. The lecture also delves into the dynamics of pendulums, comparing simple pendulums to rigid bars and analyzing the forces and motions involved. Through examples and mathematical derivations, students learn about the importance of moment of inertia in understanding rotational dynamics.
