摘 要: 介绍了一种用于课堂的多功能角动量定理演示仪,结构简单,操作方便,能演示出多种角动量定理相关实验,揭示刚体定点转动中深刻的物理规律,并采用在"自然坐标系"下的角动量定理对实验现象加以理论分析. A multi-functional demonstrating instrument of angular momentum theorem is intoduced,which is simple in structure and convenient for operating.The instrument demonstrates the related experiments of angular momentum theorem and illustrates the physical laws of the rigid-body fixed-point rotation,which is inspiring.In addition,it has the function of analyzing the experimental phenomenon with the angular momentum theorem in the natural coordinate.
