How the Calculator Works

To grasp how this calculator determines electron speed, it’s important to know the essential relationship it relies on: the kinetic energy of an electron is linked to its speed through relativistic physics principles. Using the kinetic energy entered, the electron's total energy is calculated by adding it to the rest mass energy of the electron. From this total energy, the calculator derives the velocity, taking into account the relativistic effects that become significant at high velocities.

The rest mass of an electron and the speed of light serve as constants to ensure the accuracy of calculations. The speed is determined using a formula that incorporates these constants to factor in relativistic corrections.
