We assume that they are in the standard configuration. By this we mean the frame F is moving in the x direction at constant velocity v relative to frame F. The y and z axes are the same for both observers (see Fig. 1-2). Moreover, in prerelativity physics, there is uniform passage of time throughout the universe for everyone everywhere. Therefore, we use the same time coordinate for observers in both frames. The Galilean transformations are very simple algebraic formulas that tell us how to connect measurements in both frames.

16) Now we use the fact that the transformation is linear while leaving y and z unchanged. 16). Comparison leads us to conclude that CD − AB = 0 ⇒ CD = AB D2 − B 2 = 1 A2 − C 2 = 1 To obtain a solution, we recall that cosh2 φ − sinh2 φ = 1. 18) In some sense we would like to think of this transformation as a rotation. 20) Now we solve for the parameter φ, which is called the rapidity. To find a solution, we note that when the origins of the two frames are coincident; CHAPTER 1 12 Special Relativity that is, when x = 0, we have x = vt.

Newtonian physics tells us that frame F moves with velocity v 3 = v 1 + v 2 with respect to frame F, a simple velocity addition law. However, if the velocities are significant fraction of the speed of light, this relation does not hold. To obtain the correct relation, we simply compose two Lorentz transformations.
