The video tutorial explains the concept of mass moment of inertia, a measure of an object's resistance to angular acceleration. It covers methods to calculate it, including the shell and disk methods, and the parallel axis theorem. Examples include calculating the mass moment of inertia for a cylinder, cone, sphere, slender rods, and composite bodies. The tutorial emphasizes understanding the integration process and using known equations for simple objects.
