摘要
在高中物理教学中,DIS实验变得越来越重要,本文介绍了用DIS实验观察弹簧振子在竖直方向上的振动情况,通过实验操作、观察分析、数据处理,阐明弹簧的弹力与回复力之间的关系,并计算出弹簧劲度系数κ的值,使学生更加直观地理解不同弹簧有着不同的劲度系数.笔者通过对弹簧振子的传统实验以及DIS实验的对比,不仅验证了竖直方向上形变量与回复力成正比,还对实验进行了改进与创新,总结出了使用DIS实验的优点.
The importance of DIS experiment has been increased generally in physics classroom teaching in senior high school.In this paper,we introduce the observation of vibration of spring oscillator in the vertical direction with DIS experiment.By means of experimental operation,observation,analysis and data processing,we clarify the relation between the elastic force of the spring and the restoring force,and calculate the value of stiffness coefficient,which will make students understand more directly why the different springs have different stiffness coefficient.According to the comparison between traditional experiment and DIS Lab,we can not only verify that the deformation degree is proportional to the restoring force in the vertical direction,but also give the improvement and innovation of the experiment with the advantages of using DIS Lab in teaching.
