No it's not. Your "centrifugal force" is something you invent when you (quite
wrongly) treat an accelerating reference frame as an inertial one. I strongly
suggest you go look up centripetal and centrifugal force in any first-year
university book on physics (University Physics - Benson, page 105 in the
revisited edition is one place to start) before continuing this arguement.
