Resultant Velocity Calculator

Calculate the resultant velocity from two velocity vectors (e.g., boat speed vs current).

Overview

This calculator determines the combined effect of two velocities. Common examples include a plane flying in wind or a boat crossing a river.

💡

Pro Tips

If you are crossing a river perpendicularly, the angle is 90°.
Headwind implies 180°, tailwind implies 0°.

Fun Facts

"Aircraft pilots must constantly calculate resultant velocity to stay on course."
"The 'Ground Speed' is the magnitude of the resultant velocity vector relative to the ground."

Formula: V = √(v₁² + v₂² + 2v₁v₂cosθ)
