Relative velocities (parallel direction)
The relative velocity (v_A|B) is the velocity of an object or observer B in the rest frame of another object or observer A.
In the case where two objects are traveling in parallel directions, the relative speed is given by the shown formulaRelated formulas
|vBA||relative speed (m/s)|
|vB||speed of object B (m/s)|
|vA||speed of object A (m/s)|
|c||speed of sound (m/s)|
