质点从可自由移动的凹曲面上滑下的运动轨迹问题

The problem of the locus of a particle sliding down on a horigontally free cancave surface

运用质心运动定理,分析了质点在可自由移动的凹曲面上滑下时,质点对惯性系的运动轨迹方程.并就质点的运动平面与凹曲面的交线方程分别为直线、椭圆、双曲线、抛物线等情况进行了讨论.

The possible tracks of a particle BXm_(2), sliding down along a free movable concave surface with the mass m_(1) are analyzed. The cases of stright line, ellipse, hyperbola, and parabola are given as examples.
