I was told it was p as well.
3. p for pmomentum
4. I didnt think it was P, it looks like p, but is it not roe or something?
5. no it is definately p

rho is density I think.

Isn't rho resistivity?

what's resistivity? is that rho as well, or something similar? hmm
8. rho is resistivity. In more ancient times (and this shows people's ages) it was used as a symbol for density.
9. That shows my teacher's age and not mine!

Greek p - Resistivity
Normal p - momentum
11. (Original post by bono)
Greek p - Resistivity
Normal p - momentum
ie rho = ρ (Greek p)
12. ermm, just being a bit pernickety, but

rho = ρ is the greek letter for r
and
pi is the greek letter for p

13. lol oh yeah
14. well thanks for confirming my suspicisons. honestly i dont think its too impressive that my maths teacher dont know it.

rho is definity resistivity, yer/
15. 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...
16. was that aimed at me? I normally use a little cow with red horns to represent momentum, what about other people?
17. 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.
