Homework Help: Lorentz transform

  1. Sep 23, 2005 #1
    derivating a from v (lorentz transform)
    u is the velocity in the +x direction
    u=(u-v)/(1-vu/c^2)
    du? how do you du the right side of the eq? :confused:

    What are you taking the derivative with respect to? Note that the u-time in the observed frame is not the same as the v-time in the reference frame. If you want your derivative to be Lorentz invariant you have to differentiate with respect to proper time.
