# Relativity Calculator

Written: 2002-03-30

This form will calculate Newtonian kinetic energy as well as relativistic mass, time dilation, and kinetic energy for an object of arbitrary mass and velocity. The defaults are for a 3500 pound automobile travelling at 60 miles per hour. Note that you can use scientific notation to enter large numbers, eg- 1E8 m/s for 100000000 m/s. Also note that for obvious reasons, the calculator cannot allow velocity figures equal to or greater than c.
