| 摘 要： | 通过理论结合实例分析，就内力对系统动量和角动量的作用作了初步探讨。认为在一些情况下，内力可通过改变外力能够改变系统的动量和角动量，这种作用是间接的。直接参与或最终改变系统动量和角动量的仍然是外力。

| Abstract: | In this paper,We have a preliminary approach into the effect of internal forces on momentum and angular momentum by giving out theory and analysis of examples. We consider under some cases,some internal forces of the mechanics system don't partake in the changes of momentum and angular momentum. However,under some other cases the internal force can change the momentum and angular momentum of the system by changing external,but this effect is indirect.It is still external force that partakes driectly and changes finally the momentum and angular momentum of the system. |
