对探究影响摩擦力大小因素实验的分析及改进

Improvement on the experiment of studying the influence factors of friction force

对传统的影响滑动摩擦力大小因素的实验进行改进,把物块的运动变换成下面木板的运动,并用定滑轮改变拉力的方向.使用改进后的装置不但可以降低操作的难度,还可提高实验的准确性.

The traditional experiment device for studying the influence factors of friction force was improved. The board was moved instead of the slider, and the force direction was changed by a stationary pulley. Using this improved device, the difficulty of operation was reduced, and the accuracy was improved.
