摘要
对测定刚体转动惯量的方法进行改进,避免匀减速运动时初始角速度的随意性,降低实验时阻力矩随角速度变化对实验结果的影响,减小实验结果误差。
According the problem of the method of measuring the rigid body moments of inertia,advanced therelevant improved step.By the improved method,the initial angular velocity at uniformly retarded motion wasinterdicted,and the result could avoid being influenced by resisting moment according to the angular velocity,and the error was reduced.
