    rho is resistivity. In more ancient times (and this shows people's ages) it was used as a symbol for density.

    Momentum is the thing you're talking about and it doesn't matter what symbol you use to express it. You can use a red square for all you like. It's different in different countries anyway...

    was that aimed at me? I normally use a little cow with red horns to represent momentum, what about other people?

    lol - of course it doesnt matter what symbol is used. but in order to have some consistancy and sanity ppl tend to agree to use the same one. and i was just wondering whether it was p, like i thought it was.
