    Gravity does no work on satellites or objects that go in circular orbits. The force is there but it does no work and hence no energy change/transfer. Work is defined based on energy change by work-energy theorem

      My point is that whether a force does work doesn’t depend on what the force is. It makes no more sense to say that magnetic forces do no work than it does to say that gravitational forces do no work.
