Abstract: Introducing the effective potential function of central force, A discussion of the movement track is conducted. The kinetic features of the object are developed semi-quantitatively first, and then numerically simulated to show all kinds of possible tracks visually, which results that the tracks are non-closed curves With quasiperiodicity.

Key words: effective potential curve, track, numerical simulations
