| Abstract: | This paper, based on the movement energy equation of mass point under the action of central force that inverses ratio to the square of the distance and with the combination of initial conditions,works out the kinematical equation of mass point,systematically analyses the influence different initial conditions make on movement results,and confirms initial conditions as the criteria of the movement track curve type of mass point. |
