The present work offers an experimental technique specially designed and employed to comprehend and teach the Newton’s second law and to overcome certain instructional difficulties. The apparatus is mainly comprised of two specifically designed toy cars, two force sensors, one distance sensor, a pulley, two pieces of gut, an Arduino microprocessor and an ordinary computer. Newton’s second law is experimentally validated by measuring, using the Arduino system, the accelerations from the distance–time graphs and by directly measuring the tension forces. The experimental results are also compared with theoretical calculations, indicating a reasonably good agreement. The designed apparatus can be employed as a Science Technology Engineering Mathematics teaching material within physics laboratories, to achieve enhanced understanding of Newton’s second law and dynamics.

目前的工作提供了一种专门设计并用于理解和教授牛顿第二定律并克服某些教学困难的实验技术。该设备主要包括两辆经过特殊设计的玩具车，两个力传感器，一个距离传感器，一个滑轮，两个肠道，一个Arduino微处理器和一台普通计算机。牛顿第二定律通过使用Arduino系统测量距离-时间图的加速度并直接测量拉力来进行实验验证。实验结果也与理论计算进行了比较，表明有很好的一致性。设计的仪器可用作物理实验室中的科学技术工程数学教材，
