# Special relativity (composition of velocities) Calculator

## Calculates the composition of two velocities.

Velocity of a body A v1
 km/s ≦c
Velocity of a body B v2
 km/s ≦c

Composition of velocities v
 km/s
 The compound velocity v does not exceed the velocity of light c.$\normal Composition\ law\ for\ velocities\\\vspace{5}\hspace{20} v={\large\frac{v_1+v_2}{1+{\large\frac{v_1v_2}{c^2}}}},\hspace{20}c=299792.458km/s$
