质点在不同初始条件下做有心力运动的探讨

摘要

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.%根据质点在与平方成反比的有心力作用下运动的能量方程，结合初始条件求解出质点的运动学方程，系统分析初始条件的不同对运动结果的影响，确定以初始条件作为质点运动轨迹曲线类型的判据。
