Resumen
Educação Superior::Ciências Exatas e da Terra::Física Conservation of mechanical energy, circular motion The moment of inertia for a rigid body around an axis of rotation is introduced, and related to its rotational kinetic energy. Flywheels can be used to store energy. Planets and stars have spin rotational kinetic energy, and the Crab Nebula pulsar is presented as a spectacular example
