Length contraction

  • As objects move faster in an inertial frame of reference, they will become shorter.
    • This is known as length contraction.

Length contraction formula

  • The formula once again relies on the Lorentz factor.
  • l=l0×1v2c2l = l_0 \times \sqrt{1-\frac{v^2}{c^2}}
    • l is the moving length.
    • l0l_0 is the length at rest (v = 0).
    • v is the moving velocity.
    • c is the speed of light.
