Friction. Was: Re: symbol for KE

T stands for tranlational energy, as opposed to U (or V), potential energy.

bc, who long ago memorized L = T-U

p.s. In searching for the origin (etymology?) of T and U/V, I found this:

ersonally, I also prefer something other than T for kinetic energy.
I think I could live with K, but E-sub-K seems superior to both. I'm
not passionate about the latter, however.

I have never seen T used for Kinetic Energy and agree that using T is
confusing and far from intuitive. I like E-sub-K, K and KE, in that order.
