读者陈一博问:“静摩擦力和滑动摩擦力是两个不同的名称,两者有什么区别呢?”在回答这个问题前,我们要明了静摩擦力和滑动摩擦力这两个物理概念,之后就不难明白两者的区别了.我们知道,相互挤压的物体在外力作用下有相对运动趋势时,会产生静摩擦力.如图1所示,物体A放置于物体B Reader Chen Yibo asked: “Static friction and sliding friction are two different names, what is the difference between the two?” Before answering this question, we have to understand the two concepts of static friction and sliding friction of physics, after It is not difficult to understand the difference between the two.We know that the mutual extrusion of objects under the action of external forces have a relative movement trend, there will be static friction.As shown in Figure 1, object A placed on the object B
