Homework Help: The non-relativistic behavior of particles

  1. Apr 24, 2010 #1
    hello
    When I was studing about the schrodinger equation,I read that it describes the non-relativistic behavior of particles .
    But I don't know what is the non-relativistic behavior of particles . S o I need somebody to explain this behavior .

    Hi FRANCLI! :smile:

    It means that we can define momentum = mv and energy = 1/2 mv2.

    (relativistic behavior of particles is more accurate, and defines momentum = mv/√(1 - v2/c2) and energy = m/√(1 - v2/c2), which are approximately the same as the non-relativistic definitions when v is very much smaller than c :wink:)

    thank you ,
    but if the energy is = 1/√(1 - v2/c2), and v is very much smaller than c , the enegy will be 1 ??????

    oops!

    oops! :redface: … i missed out the "m" :rolleyes:

    it should have been energy = m/√(1 - v2/c2)

    (or KE = m/√(1 - v2/c2) - m, which is approximately 1/2 mv2 when v is very small)

    (i've edited my last post, so it's correct now :wink:)
