摘要: 对于一个质点从可自由移动的光滑的凹曲面上滑下的速度、加速度和时间作了一般性讨论,建立了相应的公式.并对质点的运动平面与凹曲面的交线分别为直线、抛物线和椭圆等情况进行了具体的计算.

关键词: 凹曲面, 惯性系, 抛物线, 椭圆, 椭圆函数

Abstract: The velocity, acceleration and time of a particle sliding down along a horizontally free concave surface are discussed. And correlative formulas are deduced. Detailed calculations are done for several typical examples, in which the intersection line between the concave surface and the motion plane of the particle are straight line parabola, and ellipse, respectively.

Key words: concave surface, inertial frame, parabola, ellipse, ellipse function
