两体运动的相对动力学方程及内力功的计算

The relative dynamics equation of two-body motion and the calculation of work of internal force

导出了在无外力作用下两体运动的相对动力学方程及内力功的计算式,方便了求解有关力学问题.

This paper deduces the relative dynamics equation of two-body motion, on which there is no effect of outside force, and the calculating equation of work of internal force. The equations can be used to solve some mechanical problems conveniently.
