动量和机械能两章中的概念和规律,是力学知识中最基本、最重要的部分之一,它们即是牛顿力学的延伸,也为解决力学问题开辟了新的途径。本文是针对动量和机械能两章的对比教学探讨。
The concepts and laws in the two chapters of momentum and mechanical energy are one of the most basic and important parts of mechanics knowledge. They are extensions of Newtonian mechanics and open up new avenues for solving mechanics problems. This article is for the momentum and mechanical energy two chapters of comparative teaching.
