Velocity Addition Calculator
Free calculate resultant velocity when adding two velocities. supports both classical and relativistic velocity addition formulas.
Input Parameters
0° = same direction, 180° = opposite
Results
Enter velocities to calculate resultant
Velocity Addition Formulas
Classical (Galilean)
v_result = v₁ + v₂
Simple addition for low speeds
Relativistic (Einstein)
v_result = (v₁ + v₂) / (1 + v₁v₂/c²)
For speeds approaching light speed
Vector Addition
v_result = √(v₁² + v₂² + 2v₁v₂cosθ)
For velocities at an angle
Applications
