factor used in relativistic physics
γ:=1√1−β2
where β is normalized speed
Note 1 to entry: The Lorentz factor is used, for example, for relativistic mass m′=γm, Lorentz contraction d′=d/γ, and time dilatation .
Note 2 to entry: For the transfer of matter, .
Note 3 to entry: The coherent SI unit of the Lorentz factor is one, symbol 1.
