Harte Posted March 14, 2019 #26 Share Posted March 14, 2019 There is no such thing as centrifugal force. It is a phantom force - merely the reaction for to centripetal force, which does exist. Harte Link to comment Share on other sites More sharing options...
aztek Posted April 3, 2019 #27 Share Posted April 3, 2019 (edited) Quote Some people confuse centrifugal force with its counterpart, centripetal force, because they are so closely related. One might say they are two sides of the same coin. Centripetal force is defined as, “The component of force acting on a body in curvilinear motion that is directed toward the center of curvature or axis of rotation,” while centrifugal force is defined as, “The apparent force, equal and opposite to the centripetal force, drawing a rotating body away from the center of rotation, caused by the inertia of the body,” according to the American Heritage Dictionary.

pallidin Posted April 3, 2019 #28 Share Posted April 3, 2019 Excepting external influence, a Frisbee thrown in space will continue rotating... forever. However, since there is no such thing as "zero external influence", the Frisbee will eventually cease rotation. Link to comment Share on other sites More sharing options...
