Lorentz factor
The Lorentz factor γ is the factor by which time, length, and mass change for an object that is moving.
Explanation
The dimensionless Lorentz factor is defined as
where
Relative velocity between inertial reference frames v Speed of light c
Alternative 1
The formula was originally described as
where
Relative velocity between inertial reference frames v Speed of light c
Alternative 2
The formula can also be written as
where
Reduced speed β
Alternative 3
The formula can also be written as
where
Contraction factor, which is the inverse of γ α
Alternative 4
The formula can also be written as
where
Time t Proper time τ
