## Lorentz-Fitzgerald contraction
The contraction in length of a moving body, as measured by an observer at rest with respect to the body, by the factor 1/√(1 - ν^{2}/c^{2}),
where ν is the relative speed of the moving body and c
is the speed of light. Also called the
Lorentz contraction or Fitzgerald contraction
– the theory was proposed independently by both Hendrik Lorentz
and George Fitzgerald – it one
of the surprising effects predicted by Einstein's special
theory of relativity. Compare with time
dilation. ## Related category• SPACE AND TIME | ||||||
