===Centripetal and centrifugal force===
Another common mistake is to state that "the centrifugal force that an object experiences is the reaction to the centripetal force on that object."<ref>{{Citation

If an object were simultaneously subject to both a [[centripetal force]] and an equal and opposite [[centrifugal force]], the [[Net force|resultant force]] would vanish and the object could not experience a circular motion. The centrifugal force is sometimes called a [[fictitious force]] or pseudo force, to underscore the fact that such a force only appears when calculations or measurements are conducted in non-inertial reference frames.<ref>{{Citation
