Language:	en		Status: Standard

Term:	normalized speed
Synonym1:
Synonym2:
Synonym3:
Symbol:	$β$
Definition:	ratio of speed $v$ to speed of light in vacuum $c_{0}$ $β : = \frac{v}{c_{0}}$ , and $β = \| \vec{β} \|$ Note 1 to entry: The normalized speed for transfer of energy or information is less than or equal to 1. For transfer of matter, it is always less than 1. Note 2 to entry: The coherent SI unit of normalized velocity is one, symbol 1.
