Help on relativity

  1. Oct 2, 2005 #1
    For a particle moving in the xy plane of S, show that the y' component of the acceleration is given by ay'=ay/?^2(1-uxv/c^2)+axuxv/c^2/?^2(1-uxv/c^2)^3

    I don't know if this means that ths S and S' xy plane aren't parrellel? If so, how do you get the angle, if not how come there are two terms?

    No, the xy plane is exactly the same in S and S'. However, if the particle is not moving parallel to the x or y axis, the axes in that plane can be rotated (is that what you meant by "not parallel"?). By the way, there's a "?" showing up in you formulas on my reader. I presume that is some special character that is not being read correctly. Could you tell us what it is?

    The ? are gamma, and actually I know how to get the answer now, but could you check for me to see if the answer is correct? I get ay'=ay/?^2(1-uxv/c^2)^2+axuxv/c^2/?^2(1-uxv/c^2)^3
