## Definitions

- v = velocity
- c = velocity of light in a vacuum
- β = v / c
- m = mass
- m
_{0}= rest mass - γ = (1 - β
^{2})^{-1/2} - T = γ-1
- W = kinetic energy + rest mass energy

## Equations

- Tm
_{0}c^{2}= kinetic energy - m = m
_{0}γ (definition of relativistic mass) - p = mv = m
_{0}γv (definition of relativistic momentum) - W = γm
_{0}c^{2}= (m_{0}^{2}c^{4}+ c^{2}p^{2})^{1/2}
