引入转动惯量减小重力加速度测量的系统误差

Reducing System Error in Measuring the Gravity Acceleration by Introducing Inertia Moment

把刚体模型理论中的转动惯量等引入到单摆测量系统中进行误差修正,使系统误差减少了近60%.另外,此系统误差处理方法不但可以使学生对单摆运动有更深刻的认识,还可以扩展学生视野,培养学生将所学知识运用到实际中去的理念.

The error is corrected by introducing moment of inertia in rigid body model theory into the simple pendulum measuring system, and the system error is reduced by 60%. In addition, the system error processing method not only enables students to have a more profound understanding of simple pendulum motion, but also ex- pands the students horizons and trains students to apply the knowledge they have learned to practice.
