摘要
在利用单摆测重力加速度实验中,有复摆、空气浮力、空气阻力、摆角等多种误差因素。最大摆角的选择应将这些因素综合起来分析,否则将有失偏颇。在一种普通的实验方案下,本文针对两种情况,借助Mathematica软件,计算出了最大摆角的值。
In the experiment of measuring gravity acceleration with a pendulum, a few error factors are existed, such as complex pendulum, air buoyancy, air resistance and initial displacement. It is necessary to analyze these factors synthetically. With an ordinary experiment plan, some proper initial displacements are calculated under two different conditions.
