论文摘要
测量简单的摆的振荡可能是一个智能手机的智能手机，带有小但功能强大的加速度传感器〜：只需将电话连接到游乐场摇摆或将其挂在两个字符串上并记录数据即可。但是，问题立刻变得并不那么微不足道。要深入研究它或使运动的相图需要复杂的计算，远远超出了最年轻的学生的能力。在本文中，我们建议通过将传感器放在旋转轴处来研究摆的另一种方法。这种方法立即使数字非常接近教科书中的数字。
To measure oscillation of a simple pendulum was probably a first idea coming to mind after appearance of smartphones with small but powerful acceleration sensors~: Simply attach the telephone to a playground swing or hang it on two string as the pendulum bob and record the data. But immediately the problem becomes not so trivial. To deeply investigate on it or to make the phase diagram of the movement require complex calculations that are far beyond the capability of the youngest students. In this article we propose another way to study the pendulum by putting the sensors at the axis of rotation. This method gives immediately the figures very close to ones in textbooks.
