牛顿第二定律实验中阻尼系数测量

Research of the Measurement of Damping Coefficientin the Newton'sSecond Law Experiment

在中学或高等院校验证牛顿第二定律实验中要提高实验精度、验证实验结果,首先必须解决好摩擦力(粘滞力)的问题,文章讨论了用打点计时器及气垫导轨、光电计时系统来验证牛顿第二定律时,如何平衡摩擦力(粘滞力)的几种方法。

The experimental accuracy can be increased middle school or college. The test results can be proved. in the Newton＇s second law experiment in some At first, we must solve the friction force （the viscous force ） problem. This paper mainly introduces several methods of the balanced friction（the viscous force ） through the ticker-timer, the air track and the Photo--electric timing system.
