length contraction mathematical formula. Length contraction is the decrease in the measured length of an object from its proper length when measured in a reference frame that is moving with respect to the object. Thermal expansion can also be regarded as a fractional change in size of a materialsubstance caused by a change of temperature.
L L 0 1 v 2 c 2. Where L is the length of an object with is in relativistic speed. L0 is the proper length the length of the object in its rest frame gv is the Lorentz factor defined as.
