Overview
Relativistic velocity addition describes how velocities combine according to Einstein's Special Relativity. Unlike classical physics, the combined velocity never exceeds the speed of light.
💡
Pro Tips
In classical physics, you simply add v + u'.
In relativity, the formula ensures that if you add c to any velocity, you still get c.
This is critical for understanding particle accelerators and cosmic rays.

Fun Facts
"The composition of two velocities less than 'c' will always be less than 'c'."
"Even if two spaceships move towards each other at 0.9c, their relative velocity is only ~0.994c."
"Experimental verification includes the timing of cosmic ray muons reaching Earth's surface."
