研究最大静摩擦力和滑动摩擦力的相互关系,可以通过比较两种摩擦力的差值与摩擦力本身的关系,得知影响最大静摩擦力和滑动摩擦力的差值的因素。实验采用控制变量法,在记录了多种情况下物体所受两种摩擦力的大小后,分析对比数据,从而得出两种摩擦力存在着直接关系的结论。
Studying the relationship between maximum static friction and sliding friction can be obtained by comparing the difference between the two kinds of friction and the friction itself to find out the factors that affect the difference between the maximum static friction and the sliding friction. The control variable method was used in the experiment. After recording the magnitude of the two kinds of friction suffered by the object under various conditions, the comparative data were analyzed, and the conclusion was drawn that there was a direct relationship between the two kinds of friction force.
