摘　　要：角动量守恒定律是自然界中普遍适用的基本原理。但因角动量的概念较为抽象,学生对角动量守恒定律的学习与理解较为困难。为进一步明晰该定律,设计了一种可用于定量验证角动量守恒的便携仪器装置。该装置通过改变物体质量、物体到中心转轴的距离等变量,定量探究转动惯量的改变对角速度的影响,并验证角动量守恒定律。The Law of Conservation of Angular Momentum is a fundamental principle that is universally applicable in nature.However,due to the abstract concept of angular momentum,it is difficult for students to learn and understand the Law of Conservation of Angular Momentum.In order to further clarify the law,this paper designs a portable instrument device that can be used to quantitatively verify the Conservation of Angular Momentum.By changing the mass of the object and the distance from the object to the central axis,the device can quantitatively investigate the effect of the change in the moment of inertia on the angular velocity and verify the Law of Conservation of Angular Momentum.
