The interaction experienced by a fast electric dipole moving parallel and close to a flat solid surface is studied using the dielectric formalism. Analytical expressions for the force acting on the dipole, for random and for particular orientations, are obtained. Several features related to the dynamical effects on the induced forces are discussed, and numerical values are obtained for the different cases. The calculated energy loss of the electric dipole provides useful estimations which could be of interest for small-angle scattering experiments using polar molecules.
