摘要
测量物体运动瞬时速率实验是当代物理课程的一项重要实验。该实验可以通过测量物体相互运动瞬间的运动距离和时间,求得物体运动的瞬时速率。文章运用乐博士EV3机器人对该实验进行优化设计,研究发现,利用EV3机器人测量物体运动瞬时速率,实验误差在0.1以内,数据较为准确。而且,该实验装置方便自行设计与拼装,数字化的实验数据呈现方式使得实验结果更科学化,实验方法与步骤也得以有效简化,丰富了测量物体运动速率实验的形式。
The experiment of measuring the instantaneous velocity of an object is an important experiment in the contemporary physics curriculum.In this experiment,the instantaneous velocity of objects can be obtained by measuring the instantaneous distance and time of objects moving with each other.This paper uses Dr.Lee’s EV3 robot to optimize the design of the experiment.It is found that the experimental error of measuring the instantaneous velocity of object motion with EV3 robot is within 0.1,and the data is more accurate.In addition,the experimental device is convenient for self design and assembly.The digital experimental data presentation mode makes the experimental results more scientific,and the experimental methods and steps are also effectively simplified.At the same time,it enriches the forms of experiments for measuring object motion speed.
