Abstract: We consider SG-kink motion under the ac external force and dissipation assuming that kink shape conserves, and the kink velocity is changing in time. External forces are harmonically dependent upon time and are considered as step functions.

Keywords: kink, sinus-Gordon equation, ac external force.
