【摘要】 文中利用视频捕捉和分析软件研究空气中弹簧振子的阻尼运动,在较高时间分辨率下得到其完整的位置数据。通过使用MATLAB软件对这些数据进行分析及拟合,得到了振子振幅衰减曲线并由此测量出弹簧振子在空气中的阻尼系数。更多还原

【Abstract】 The free damped oscillation of a spring oscillator in air is captured by video camera and analyzed by Tracker software. The whole oscillation is recorded under a relatively high temporal accuracy. By extracting and fitting the damped curve of the amplitude versus time using Matlab codes,the damped coefficient of the setting is obtained.更多还原
