This video demonstrates the calculation of the moment of inertia, progressing from discrete particle systems using summation to continuous mass distributions using integration. It specifically derives the moment of inertia for a uniform disk rotating about its diameter using polar coordinates and area elements, concluding with the formula I = 1/4 MR².
