Relativistic Dynamics, or "Why can't the electron go faster than the photon?"

    We will investigate the dynamics of objects as they move faster and faster, and compare the results with the classical equations.
    There is a "universal speed limit" of the speed of light - all material objects must go slower than this speed (only light can go at that speed). Because of this, to make an object go faster, you have to dump more energy into than you thought (more than under the classical rules).
    The classical curve is plotted in red. The c speed limit is the horizontal blue line. The relativistic (correct) line is black.
    You can change the parameters below, to investigate the results. Your current configuration is shown as the blue dot on the graph.

Classical Values : Mostly absurd!	Relativistic Values : REAL!	Ultra-Relativistic Values : Approximate!
	E(rel) = MeV
P(class) = MeV/c	P(rel) = MeV/c	P(ultra) = MeV/c
v(class) = c	v(rel) =
Error (classical vs relativistic) = %		Error (ultra vs relativistic) = %

Choose which configuration :

     Set the initial parameters of the particle:
      Electron       Proton
       KE =     MeV

Here are the equations we will use ...
