Beta (velocity)

β in special relativity is the velocity, v, of an object relative to the speed of light c:^[1]

${\textstyle \beta ={\frac {v}{c}}}$

It is less commonly referred to as the Jackson Number.^{[citation needed]}

β is dimensionless and equal to the velocity in natural units. Any expression which involves v, like the Lorentz factor, can be rewritten using β instead. See the Lorentz transformation.
