What is Moment of Inertia (And Why Mass Resists Rotation)

A rigorous mathematical breakdown of the moment of inertia and rotational dynamics. This video demonstrates how to calculate the integral for continuous solid shapes, explaining mathematically why a hollow hoop resists rotation more than a solid disk of identical mass. We analyze how geometric arrangement scales tangential velocity and torque, forcing rotational inertia to scale quadratically with distance. References: 1.
