According to special relativity, a rod of length L moving at velocity v will shorten by an amount 8, given by:
δ = L(1 - √1 – v2/c2
where c is the speed of light (about 300 x 106 m/s). Consider a rod of 2 m long, and make three plots of 8 as a function of v for 0 < v < 300 x 106 m/s. In the first plot use linear scale for both axes. In the second plot use logarithmic scale for v and linear scale for δ, and in the third plot use logarithmic scale for both v and δ. Which of the plots is the most informative?
