What happens to centrifugal force as speed increases?

The outward effect seen in a rotating frame grows with speed because centrifugal force is proportional to v^2 for a given mass and curve radius. In circular motion, the required inward (centripetal) force is F = m v^2 / r, so as speed increases, the inward demand rises and the corresponding outward (centrifugal) tendency strengthens. If you double the speed around the same curve, the centrifugal force becomes four times larger. It does not stay the same or disappear; it increases with speed.
