摘要
在传统刚体转动惯量实验仪器的基础上,用弹簧代替砝码,用手机拍摄实验过程,用Tracker和Origin软件处理实验数据,来研究刚体转动惯量.考虑加速度、摩擦力矩等因素的影响后,系统误差减少,并实验测量了摩擦力矩.
The traditional experimental device of moment of inertia of rigid body was improved by replacing the weight with a spring.A video of the experimental process was recorded by a mobile phone,the data were processed by Tracker and Origin.The influence of acceleration and friction moment was taken into account,and the friction moment was measured.
