Nowadays, mechanical experiments such as spring oscillations for high schools and colleges have been developed using smartphones. This study aims to compare the use of acceleration sensors and video tracker available on smartphones for free and damped spring oscillation experiments. This experiment used varying load masses. In experiments using acceleration sensors, acceleration versus time data were obtained, while experiments using a video tracker got position versus time data. The data were then calculated to obtain the spring constant value and the damping coefficient are obtained. The experimental results showed that for experiments using the acceleration sensor, the spring constant values k = (11.8 ± 0.2) N m −1 . For experiments using a video tracker the spring constant values k = (12.1 ± 0.4) N m −1 . Experiments using the acceleration sensor can explain the acceleration trends that change periodically whereas when we use a video tracker i...

在智能手机上使用加速度传感器和视频跟踪器进行弹簧振荡实验的比较

如今，已经使用智能手机开发了机械实验，例如高中和大学的弹簧振荡。这项研究旨在比较智能手机上可用的加速度传感器和视频跟踪器在自由和阻尼弹簧振荡实验中的使用情况。该实验使用了变化的负载质量。在使用加速度传感器的实验中，获得了加速度与时间的数据，而使用视频跟踪器的实验中获得了位置与时间的数据。然后计算数据以获得弹簧常数值并获得阻尼系数。实验结果表明，对于使用加速度传感器的实验，弹簧常数值k =（11.8±0.2）N m -1。对于使用视频跟踪器的实验，弹簧常数值k =（12.1±0.4）N m -1。
