1. The problem statement, all variables and given/known data A frame is accelerating uniformly along the x-axis relative to an inertial frame (x,y,z) with acceleration a.Find the transformation between the frames given that the origins concide at t=0. 2. Relevant equations The lorentz transformations cannot apply here ,but what equation has to be used ? 3. The attempt at a solution I think a tensor equation is what we need because tensor equations i.e maxwell equations in tensor notation are frame invariant.
