Conceptual Physics
... Centrifugal force is an effect of rotation. It is not part of an interaction and therefore it cannot be a true force. For this reason, physicists refer to centrifugal force as a fictitious force, unlike gravitational, electromagnetic, and nuclear forces. Nevertheless, to observers who are in a rotat ...
