在初中物理知识点中,有好多地方用到了各种物理方法。下面就物理方法在知识点教学中的运用方法做一总结。一、控制变量法控制变量法是在研究某个物理量受那些因素影响时,一般先控制其他的因素不变,讨论其中一个因素的影响。在初中物理中这种方法运用的比较多。例如:在“研究滑动摩擦力的大小和哪些 In junior high school physics knowledge point, there are a lot of places used a variety of physical methods. Here's a summary of how physical methods are used in knowledge point teaching. First, the control variable method Control variable method is to study a physical quantity by those factors, the general control of the other factors remain unchanged, discuss the impact of one of the factors. In junior high school physics this method is used more. For example: ”Study the size of sliding friction and what
