Work - Energy theorem in rotational reference frames
In standard textbooks of college physics, Theorem of Work and Energy is generally presented for inertial reference systems in which it is clear that the kinetic energy is conserved when there is not net work of the forces of interaction. But what happens when energy and work are calculated on a non-...
