Abstract
Sine-Gordon kinks under the influence of a constant force do not travel along the classical trajectory. It is shown here that solitons and kinks which obey one of the nonlinear Schrödinger equations and which are also subject to a constant force, on the contrary, do travel along the classical trajectory.Keywords
