摘要
对摆绳阻力进行了定量分析。综合考虑单摆系统的空气阻力、摆绳重力及复摆因素后,借助MATLAB软件,用数值计算的方法对单摆运动进行了动力学描述。通过与实测数据比较发现,理论计算结果与实测值符合得很好。为此,为确定实际单摆实验的最佳摆角提出了一种依据。
Air drag of the wire of a simple pendulum was quantitatively analyzed.By taking air drag forces of the wire and the ball,gravity of the wire into consideration,the dynamics of a simple pendulum as a compound pendulum was discussed by a numerical method with MATLAB.Theoretical results are in good agreement with the experimental data.Accordingly,some advice about the simple pendulum experiment is proposed.
