物体的受力分析是贯穿力学乃至高中物理的一条红线,它是学习力学知识的基础,是横在高中学生面前的一道门槛,跨不过它,高中物理将很难过关,所以正确分析物体的受力情况是研究力学问题的重要方法和关键环节。在此,我就将自己指导学生进行物体受力分析并取得良好成效的方法给广大学生作一介绍,以有助于学生的学习。一、受力分析的定义受力分析指依据力的概念,从物体所处的环境(有多少个物体接触)和运动状态着手,分析它与所处的环境和其他物体的相互联系。二、受力分析的一般步骤1.明确研究对象并把它从周围的环境中隔离出来
The force analysis of objects is a red line that runs through mechanics and even high school physics. It is the basis for learning mechanics knowledge and a threshold across high school students. Crossing it, however, high school physics will be hard to pass through, so the correct analysis of objects Force situation is an important method and key link in the study of mechanics problems. Here, I will give my students a guide to stress analysis and get good results for students to help students learn. First, the definition of stress analysis Force analysis refers to the concept of force, according to the object in which the environment (how many objects contact) and the state of motion to start with it to analyze the environment and other objects in contact with each other. Second, the general steps of stress analysis 1. Clearly study the object and isolate it from the surrounding environment
