Effectively, your non-existent brain has locked in the garbage you had accepted so readily, because you weren't smart enough to catch all of the errors. One of the biggest errors is that the 'units' must be different for every single equation. FACT: "Pounds" satisfies the only important 'answer' to: Force; momentum; KE; PE ( but is manifested only by having a distance of fall, and which accrues only as the object falls); and power. The latter, power, is simply a FORCE that can be utilized for some variable period of time, it is unnecessary to have time of usage be indicated in the 'units'. An engineer only needs to know the torque (or unit rotational force) on a shaft to compute how much FORCE (power) is available at a given electric meter. The meter does the "time of usage" calculations, so the 'units' can simply be FORCE in POUNDS! Know this, fellow, the simple and consistent definitions are the best. It doesn't take a brain to learn that most of the 'units' in mechanics are pounds of force. But you just can't get it, can you.

Well, no, wrong again. What I accept is what has been experimentally verified. Your formulas are wrong and do not agree with millions of well done experiments. Therefore they are wrong.
