摘要
本文从时空对称性的原理出发,在经典力学的范围内,讨论了动量守恒定律和角动量守恒定律.并讨论了在非惯性系特别是质心坐标系中动量守恒和角动量守恒的问题.
A discassion has been made on the law ot cdnservation ot momentum and angular momentwm within the liawts ot classcal meohanics based on principle ot the symmetry ot time and space.The problem has been discussed ot the lew ot conseruatiou ot mementum and angular momentwm inthe inertialess coordinatcs,especially in the center—andmass coordrnates.
