摘要

我们使用Arduino和相关的双轴加速度计传感器作为测量装置进行了复摆实验。我们已经证明，使用加速度计来测量摆锤在沿其轴线的不同位置处的径向和轨道加速度，与摆锤实验的常规分析相比，提供了进行更复杂分析的可能性。通过这种方式，我们已经证明了这个经典实验可以带来一个有趣且低成本的力学实验。

Physical pendulum experiment re-investigated with an accelerometer sensor

We have conducted a compound pendulum experiment using Arduino and an associated two-axis accelerometer sensor as measuring device. We have shown that the use of an accelerometer to measure both radial and orbital accelerations of the pendulum at different positions along its axis offers the possibility of performing a more complex analysis compared to the usual analysis of the pendulum experiment. In this way, we have shown that this classical experiment can lead to an interesting and low-cost experiment in mechanics.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
