Relative Velocity

One must take into account relative velocities to describe the motion of an airplane in the wind or a boat in a current. Assessing velocities involves vector addition and a useful approach to such relative velocity problems is to think of one

Put into words, the velocity of A with respect to C is equal to the velocity of A with respect to B plus the velocity of B with respect to C.
