AI总结:

利用智能手机压力传感器和环形磁铁测量磁力,验证牛顿第三定律中作用与反作用力的大小相等、方向相反。

摘要:

本文介绍了一种利用 readily available 技术教授牛顿第三定律的新方法。通过使用智能手机的压力传感器、两个环形磁铁和日常用品测量磁力。学生可以测量力的大小,更直观地理解该定律,并观察'作用'和'反作用'如何在量上相等且方向相反。

英文摘要:

A fascinating approach to teaching Newton's Third Law using readily available technology is presented in this article. Magnetic forces are measured by using a smartphone's pressure sensor, two ring magnets, and common household items. Students can measure the magnitudes of forces, gain a more tangible understanding of the law, and see how 'action' and 'reaction' are quantitatively equal and opposite.
