摘要

以 Arduino UNO为主控单元，在运动小车中装载智能测量系统，用力传感器测量合外力，超声波传感器实时测量小车与固定挡板间的距离，并根据距离数据计算速度和加速度，实现对传统的验证牛顿第二定律实验装置的智能化设计。系统操作简便、测量精确，能实时显示实验结果，在遵从传统实验思路的基础上大大提高实验效率。

Abstract:

With Arduino UNO as the main control unit, the moving car is loaded with an intelligentmeasurement system.The resultant external force is detected by a force sensor, while the distance between thecar and the fixed baffle is measured by an ultrasonic sensor in real time.As a result,the speed and accelerationare calculated from the distance data.The traditional experiment to verify Newton's Second Law has beenintelligently improved and designed. The system is easy to operate ,accurate in measurement,and can displathe experimental results in real time , which greatly improves the experimental efficiency on the basis offollowing the traditional experimental process.

Key words: Newton's Second Law ntelligent acceleration resultant force
