We show a formal result of the longitudinal force acting on a moving potential. The potential can be velocity dependent, which appears in various interesting physical systems, such as electrons in the presence of a magnetic flux line, or phonons scattering off a moving vortex. By using the phase-shift analysis, we are able to show the equivalence between the adiabatic perturbation theory and the kinetic theory for the longitudinal force in the dilute gas limit.
