12  RELATIVISTIC KINEMATICS

12.1 Introduction

The special theory of relativity demands that we examine and modify the familiar results of newtonian physics. We must start by reconsidering kinematics, the most elementary aspect of mechanics, a topic apparently so simple that we gave little thought to its foundations in our earlier discussion. As we pointed out in the last chapter, classical kinematics obeys the Galilean transformations. We must now develop the kinematics appropriate to the Lorentz transformations.

The Lorentz transformations are simplified by introducing

Since (v/c)2 ≤ 1, γ is greater than or equal to one. The Lorentz transformations, ...
