摘要
角动量守恒定律是自然界中最普遍最基本的守恒定律之一。首先介绍了角动量的概念和角动量守恒的条件,然后阐述了角动量守恒定律在直升机、鱼雷、子弹和炮弹、定向导航等军事技术中的广泛应用,在军校大学物理教学中适当引入军事案例能提高学员的学习兴趣。
The conservation law of angular momentum is one of the most universal and basic conservation laws in nature.This paper introduces the concept and conservation conditions of angular momentum at first,and then expounds the wide application of the conservation law of angular momentum in military technology such as helicopter,torpedo,bullet and shell,directional navigation,etc.The introduction of military cases into college physics teaching in military academy can improve students'interests in learning.
