There's no such thing as "the force of a mass moving at a velocity". Something weighing 1 lb moving at 5 mph does not have a force, much less a force of 1x5x5 or 25 lbm^2/h^2. Force does not equal mass times velocity squared. Force is MEASURED in equivalent terms, but Force equals mass times ACCELERATION, which, for a mass moving at a constant velocity, is zero.
