Einstein’s Theory of Special Relativity (HSC SSCE Physics): Flashcards

1905

Laws of physics same in all inertial frames

Speed of light constant in all frames at $c$

$3.0 \times 10^8 \, \text{m s}^{-1}$

$t = \frac{t_0}{\sqrt{1-\frac{v^2}{c^2}}}$

Time interval between events at same place in frame

$\gamma = \frac{1}{\sqrt{1-\frac{v^2}{c^2}}}$

$l = l_0\sqrt{1-\frac{v_0^2}{c^2}}$

Only in direction of relative motion

Both are reciprocal between reference frames
