# Centrifugal force fiction

A claim of the existence of a ‘centrifugal force‘  is not strictly a logical fallacy, except when it is argued to be a real force. It is actually a fictional force that appears to draw a rotating body away from the center of rotation. It is caused by the inertia of the body, which would otherwise continue in  the direction of a straight line, if it were not for the constraining force causing  the body to rotate about the centre. Professor Julius Sumner Miller entertainingly demonstrates these forces here:

It’s not a fictional force, Tim. It’s the other half of a pair that includes a centripetal force. Unless of course you are ditching Newtons third law and the law of conservation of momentum.

With regard to centrifugal force you say: “It is actually a fictional force that appears to draw a rotating body away from the center of rotation.”

This is not true, a centrifugal force is the outward radial force “EXERTED” by a rotating mass, just ask Newton.
