During typical general relativity courses, the so-called frame-dragging effect is explained by emphasizing the presence of a gravitational Coriolis-like force term. The key difference is that, unlike the usual Coriolis force, this is not a fictitious force but agravitational force caused by the rotating body. In general, textbooks do not discuss also the possibility of a gravitational centrifugal-like force. In this paper, which has a didactic aim, we analyze this further gravitational term. The analysis we perform can be valuable in undergraduate courses of general relativity.

Abstract
During typical general relativity courses, the so-called frame-dragging effect is explained by emphasizing the presence of a gravitational Coriolis-like force term. The key difference is that, unlike the usual Coriolis force, this is not a fictitious force but agravitational force caused by the rotating body. In general, textbooks do not discuss also the possibility of a gravitational centrifugal-like force. In this paper, which has a didactic aim, we analyze this further gravitational term. The analysis we perform can be valuable in undergraduate courses of general relativity.File in questo prodotto:
