Simple Nature - Light and Matter

Exercise 7B: Sports in Slowlightland


In Slowlightland, the speed of light is 20 mi/hr≈32 km/hr≈9 m/s. Think of an example of
how relativistic effects would work in sports. Things can get very complex very quickly, so try
to think of a simple example that focuses on just one of the following effects:



  • relativistic momentum

  • relativistic kinetic energy

  • relativistic addition of velocities

  • time dilation and length contraction

  • Doppler shifts of light

  • equivalence of mass and energy

  • time it takes for light to get to an athlete’s eye

  • deflection of light rays by gravity
