Abstract

Einstein’s special theory of relativity modifies the Newtonian concepts of energy and momentum so that they correctly describe bodies moving at high speeds. The modifications lead to the best-known prediction of the theory of relativity: Energy has mass and vice versa, E = mc2, and they also show that the relationship between kinetic energy and momentum that you have frequently used \(K\, = \,\frac{{{p^2}}}{{2m}}\, = \,\frac{1}{2}m{v^2}\), is only an approximation of the equations that are exact at all speeds. You now need to become familiar with the relativistically correct relationships and how they are used to extract information about atoms and the particles they are made of.
