Keywords:

  • Relativity 1 - space and time;
  • Newton's theory - was, and is, outstandingly successful;
  • Galilean Relativity - mechanics experiments, cannot distinguish between inertial frames and relativistic principles operating within a Newtonian framework;
  • geometric ‘analogy’ - in understanding frame changes in relativity;
  • fundamental postulates of relativity;
  • laws of nature - the same for all inertial observers;
  • Michelson–Morley experiment, velocity of light being isotropic - or the same in all directions;
  • inertial observers in relativity;
  • comparing transverse distances - between frames;
  • principle of relativity, correct way of relating space–time coordinates of events in one frame
