摘要
基于落球法测量液体黏度的传统实验仪器,用手机拍摄小球下落过程,利用视频分析软件Tracker分析捕捉分析小球下落过程中位移和速度.通过处理数据,结果表明此方法能直观显示小球下落运动规律,获得的终极速度、黏度等数据更加准确.
Based on the traditional falling-ball apparatus of measuring liquid viscosity,the falling process of the ball was video recorded by a smart mobile phone,and the displacement and velocity of the ball were processed using the intelligent video Tracker software.The analysis of motion of the falling ball could be displayed directly and the obtained terminal speed and viscosity coefficient were more accurate.
