Wouldn't make any difference, because the entire concept is flawed in the
first place.  There's no such thing as "centrifugal force"; what normally
goes by that name is really just inertia.  You feel "centrifugal force"
when whirling a mass on a line around simply because you have to accelerate
the mass *inward* to get it to follow a circular course - by itself, the
mass at all times "wants" to keep moving in a direction tangential to the
circle.  The distinction is usually only for the pedantic, until we start
talking about such things as "harnessing the centrifugal force."
