| Abstract: | In this paper, we consider problem of the existence of periodic solutions for a system of second order ordinary differential equations that model the motion of two particals on the real line. And we obtain the the necessary and sufficient conditions for the existence of periodic solutions under some sublinear condition for the restoring force. |
