From: NoEinstein on 6 Nov 2009 11:30 On Nov 3, 6:51 pm, PD <thedraperfam...(a)gmail.com> wrote: > Dear PD, the Parasite Dunce: According to the current 'science' stupidity, if force of impact (momentum) varies in proportion to the velocity of the impacting object, then the "units" must = pound-feet/ second. A quantity can vary in proportion to something else WITHOUT having that 'something else' showing up in the units! Suppose that the cost of an item on sale goes up in direct proportion to wealth of the buyer. Then, the stated sales price would be dollars-dollars/year or dollars ^2 per year. NO! The cost is expressed just in dollars without anyone needing to know that the price will get inflated if the buyer is rich! The problem with 'just' equations is that people loose track of what it is that is being measured. If a football player weighing 200 pounds blocks a lineman weighing three hundred pounds, there is a velocity at which the 200 pounder can equal or exceed the momentum of the more-or-less stationary lineman. Effectively, momentum is just an increase in hitting power (pounds) caused by velocity. My Wiley Engineering Desk Reference indicates that Work (W) = Fs foot-pounds. Then, it indicates that Kinetic Energy (W) = ½ mv^2. Setting the two Ws equal yields: Fs foot-pounds = ½ mv^2. But that equation VIOLATES the Law of the Conservation of Energy! Why? Because the KE equation is, and always has been WRONG! The links below explain why.

The only resistance offered by a falling object is that object's INERTIA, which remains constant throughout the fall. Most of the... distance of all is COASTING due to the velocity carry-over from precious seconds. The rate of change of the velocity in all near- Earth falling objects is uniform or LINEAR. Since MOMENTUM varies in proportion to the change of velocity, then, momentum must be increasing LINEARLY, too. KE and Momentum are IDENTICAL animals. My $40.00 KE experiment invalidates Coriolis's KE = 1/2 mv^2, as does the Law of the Conservation of Momentum. Give it up, fellow. I've shot Coriolis and Einstein all to hell!
