Relative Velocity Components Used to calculate the components of the velocity of object A relative to object B in two-dimensional motion. Define the relative velocity vector v A/B as the difference between the absolute velocity vectors v A and v B . Resolve the absolute velocities into orthogonal components (x and y). The relative velocity component along the x-axis is found by subtracting the x-components: v A/B,x = v Ax - v Bx . Similarly, the relative velocity component along the y-axis is found by subtracting the y-components: v A/B,y = v Ay - v By . All velocities must be defined in the same coordinate system. The relative velocity vector components are calculated independently for each axis. Confusing relative velocity with vector addition (it is subtraction). Forgetting to resolve the velocities into components before subtraction. Assuming the magnitude of the relative velocity is simply the difference of the magnitudes ( |v A - v B| ).
