Average velocity

  1. Dec 21, 2009 #1
    Hello:smile:
    suppose we have a gas (ideal) inside that gas there are particles ([tex]N[/tex]
    particles) and each particle has a certain velocity [tex]v[/tex].
    i want to find the average velocity of all the particles inside that gas.
    would it be [tex]\mathbb{V}=\frac{\sum_{1}^{n}v_i}{N}[/tex]
    [tex]\mathbb{V}[/tex] the average velocity.
    thanks.

    Wouldn't the upper limit on the sum also be N?
