| 摘 要： | 在不同惯性系中对功和能量进行计算时,由于动能的计算在坐标变换中出现了交叉项,使它们的物理意义产生了混乱。本文通过对碰撞问题的分析,指出动能和势能一样,属于相互作用的整个物体系统,在一个真实的物理过程中,必须选择质心坐标系,才能正确地计算出各物体的动能和动能变化。

| Abstract: | When the work and energy of bodies are calculated in different inertial systems, a confusion of physical siguificaues is often caused by the cross terms in the kinetic energy formula (for the coordinate transformation ) . In this paper, through the analyses of a collision process it is pointed out that the kinetic energy of bodies just as their potential energy belongs to the whole interacting system, and in a real physical process the kinetic energy of every body and its change must be calculated in the mass-ceuter coordinates for getting correct results. |
