vitality00 Posted November 4, 2014 Share Posted November 4, 2014 The formula I am using says that it is a non-relativistic equation and to calculate velocities near the speed of light I have to transform it somehow to make it relativistically accurate (something like that) Link to comment Share on other sites More sharing options...
elfmotat Posted November 4, 2014 Share Posted November 4, 2014 A non-relativistic equation is invariant under Galilean boosts. (See here.) A relativistic equation is invariant under Lorentz boosts. (See here.) When the velocities in the problem you're considering are much smaller than c, Lorentz transformations and Galilean transformations become approximately the same thing. (More formally, Lorentz transformations and Galilean transformations are equal in the limit where (1/c)->0.) 1 Link to comment Share on other sites More sharing options...
