What is the difference between Lorentz transformations and proper time

mercredi 2 juillet 2014

Hi all,

What is the difference between Lorentz transformations and yt?. That is, the Lorentz transformations for moving between two reference frames are not the same as the relativistic ones.



For example considering a frame F that is stationary and an inertial frame F' with velocity v. Time dilation for frame F' is given by yt, where gamma is the relativistic factor. But the Lorentz transformations give y(t - [xv/c2 ]). These are obviously different. So which one is correct? Or is time dilation a special case of a transformation? And Length contraction is also not the same as space transformations. So is it a special case as well?

Thanks for any answers.
