三线摆实验中学生易犯错误和解决方法的探讨

Secondary School Students' Pitfalls and Solutions in Three-wire Pendulum Experiment

以多次的用三线摆测定物体转动惯量的实验教学工作为基础,总结了一些学生在用三线摆测物体的转动惯量实验中容易出现的问题和解决的方法,从转动、物理天平以及表格的数据处理等方面来阐述问题及解决方法.

Based on the experimental teaching of using three-wire pendulum to measure the moment of inertia of objects for many times, this paper summarizes some pitfalls and solutions of secondary school students in three-wire pendulum experiment and points out that these problems can be solved from three aspects： rotation, physical balance and data processing forms.
