Homework Help: The unit of momentum

  1. Feb 27, 2007 #1
    what is the unit of momentum?

    i know that p=mv which has units of kg*m/s but is there another way to write it?

    AFAIK, there isn't a unit for momentum named after a famous scientist, if that's the kind you're asking for - (like Energy = Kgm^2/s^2 = Joule).

    is there a way to write it using newtons?

    A Newton is equal to 1 kg*m/s^2

    So I guess theoretically you could give momentum in Newton seconds (as this would effectively cancel one of the "seconds"), but that seems pointless to me.

    although it does seem pointless, I've seen it used and I believe N*s is acceptable

    I'll be damned. Interesting
