There really is no such thing as centrifugal force, although I doubt that
people who haven't studied high-school physics would be happy with 'absence
of centripital force'.

There is often a gap between everyday usage and the correct physical
explanation.

The property which most railway people call momentum (as in momentum
grades) is actually kinetic energy.
