摘要
在传统的用三线摆测量刚体转动惯量实验的基础上,用手机拍摄实验过程进行实验数据的采集,利用Tracker视频分析软件和C语言程序来处理实验数据,研究刚体的转动惯量;与传统的通过秒表读取三线摆摆动周期相比,使用Tracker软件处理实验数据可以节约实验时间,更大的优势在于可以避免人工读数产生的误差,从而提高实验精度。
Based on the traditional three-line pendulum method of measuring the rotational inertia of the rigid bodies, obtaining experimental data by recording the experimentation using an intelligent mobile phone and processing the data with the intelligent video Tracker software and C Language Programming can be a good way to study the rotational inertia of the rigid bodies. Comparing with the traditional data of the cycle of three-line pendulum obtain by a stop-watch, processing the data with the intelligent video Tracker software saved a lot of time, with a greater advantage is that it can avoid the artificial reading error, and the experimentation is thus more accurate.
