Spec Rel: Changes in gradient between frames

  1. Mar 19, 2012 #1
    1. The problem statement, all variables and given/known data
    Suppose a rod measured in the S frame has a gradient of M.

    The S' frame travels at v (along x-axis) relative to S. What is the gradient of the rod in the S' frame?


    2. Relevant equations
    Lorentz tranformations


    3. The attempt at a solution


    y'=y


    x' = [itex]\gamma[/itex](x-vt)


    so that m = y'/[itex]\gamma[/itex](x-vt)


    This seems straightforward enough, which is why I'm worried. I'm not used to problems in relativity being this easy. Have I missed anything?
