And, "also", you forgot to provide evidence that foot pounds is not a commonly accepted and practiced method of expressing kinetic energy.
Aside from that, great post!
You're the internet expert apparently. I don't think I need to provide evidence that kinetic energy is not measured in foot-lbs anymore that I need to provide evidence that distance isn't measured in bushels. You clearly have no idea what you're talking about. I cite your posts as evidence of this.
