Light and Special Relativity

These questions cover the special relativity skills that school trial papers test again and again: inertial frames and the postulates, simultaneity, time dilation, length contraction, muons, trips to stars, relativistic momentum and $E=m{c}^2$. Use $c=3.00\times 10^8$ m/s. They start easy and get harder. Stuck? Tap Show a hint for one step at a time.
