Homework Help: What is momentum?

  1. Feb 24, 2009 #1
    1. The problem statement, all variables and given/known data

    What is momentum? How do you find it?

    2. Relevant equations

    3. The attempt at a solution
    I think that momentum is massxvelocity.... but what is it? the definition? dictionary.com says that it is... theforce or speed of movement; impetus, as of a physical object or course of events....
    but that isn't right because momentum isn't velocity and velocity is speed w/ direction... momentum is speed,direction and force combined.... but what is momentum? the definition?

    The quantity of motion which is found by multiplying mass by velocity.

    To me its somewhat hard to define as its more of a concept with practical uses.
