کروند ِ لورنتز karvand-e Lorentz
*Fr.: facteur de Lorentz*
In → *special relativity*, an important parameter which appears
in several equations, including → *time dilation*,
→ *length contraction*, and
→ *relativistic mass*. It is defined as
γ = 1 / [1 - *(v/c)*^{2}]^{1/2} = d*t*/dτ,
where *v* is the velocity as observed in the reference frame where time *t*
is measured, τ is the proper time, and *c* the
→ *velocity of light*. Same as *Lorentz γ factor*. → *Lorentz*; → *factor*. |
