Rotational Inertia

Mr. Anderson explains rotational inertia and angular momentum, focusing on how they are calculated and their applications. He discusses the conservation of angular momentum, the role of mass and radius in determining rotational inertia, and provides examples using flywheels and records. The video also explores the concept in the context of satellites and planetary orbits, highlighting how changes in position affect velocity due to conservation laws.
