在我们的生活和生产中,摩擦力无处不在。有时是有利的,我们常常增强它的作用,有时是不利的,我们常常减弱它的作用。而在中学物理第一册中所讲的几种力当中,最难分析的就是摩擦力,但在几种摩擦力中最容易被学生忽视的还是静摩擦力,所以现就静摩擦力问题进行如下简要探讨,以供物理初学者学习时参考。一、静摩擦力概念的探讨与分析提出问题:滑动摩擦力是一个物体在另一个物体表面上有相对滑动的时候发生的,互相接触的两个物体处于相对静止的
Friction is everywhere in our lives and production. Sometimes it is advantageous that we often enhance its effect, sometimes unfavorable, and we often weaken it. Among the several kinds of forces mentioned in the first volume of high school physics, the hardest part to analyze is friction, but the static friction is the most easily overlooked by students in several types of friction. Therefore, Explore for reference for beginners to learn physics. First, the discussion and analysis of the concept of static friction Ask the question: Sliding friction is the occurrence of a relative sliding of an object on the surface of another object, the two objects in contact with each other in a relatively static
