摘　　要：介绍了设计性实验"利用刚体转动惯量实验仪验证转动定律".该实验要求学生理解刚体动力学原理;利用实验室现有的仪器,对刚体转动惯量实验仪进行改装;提出新的实验原理,可以对阻力矩进行估测,利用该实验装置验证刚体定轴转动定律.Design of experiment ＂validation of the rotation law using experimenta[ instrument for the moment of inertia of rigid body＂ is introduced. The experiment requires students to understand the dynamics principle of rigid body, and modify the experimental instrument for the moment of inertia of rigid body using the existing instruments in laboratory. New experi- mental principle is put forward, and the moment of resistance can be estimated. The law of fixed axis rotation of rigid body is validated by this experimental device.

关 键 词：设计性实验 刚体定轴转动定律 转动惯量 阻力矩 改装
