力学是初中物理的重要内容。能够正确分析物体的受力情况,是解决力学问题的出发点和关键所在。但是对物体进行受力分析牵涉的知识面广、综合性强,部分学生在进行受力分析时感到困惑。其实对物体进行受力分析是有章可循的,只要运用得当还是能很快掌握的,现本人结合多年的教学经验来谈谈物体的受力分析如下:第一步,明确被研究对象,看看被研究的是什么物体或是哪个物体,一般来说被研究的对象就是指受力物体。受力物体顾名思义
Mechanics is an important part of junior high school physics. Being able to correctly analyze the force situation of an object is the starting point and the key to solving the mechanics problem. However, the force analysis of objects involved in a wide range of knowledge, comprehensive, some students feel confused in the analysis of force. In fact, the force analysis of objects is a rule-based, as long as the use of properly or quickly grasp, now I combine years of teaching experience to talk about the object force analysis is as follows: The first step is to be clearly the object of study, Look at what is the object of study or which object, in general, the object of study refers to the force object. Force object as the name suggests
