摘要
分析了正比于转动角速度的黏滞摩擦对刚体转盘转动的影响,给出了转盘在黏滞摩擦下加速转动和自由减速转动的角速度公式,并利用Tracker视频分析软件对转盘的转动进行了分析,验证了所给出公式的正确性并在较高精度下测量出了系统的转动惯量.
The influence of a frictional torque to the rotation of a rigid disk is analyzed. The equation of the disk＇ s rotation movement are given. Based on these analyses, the experimental research of the disk＇ s rotating is carried out by using video capture and Tracker software. The experimental results confirm the theoretical analyses and give the momentum inertia of the disk in a relatively high precision.
