一、平衡物体的受力分析物体受力分析就是把选定的物体(即研究对象)在特定的物理情景中所受到的力找出来,并画出受力图.对物体进行正确的受力分析是解决力学问题的基础,并且受力分析思想还贯穿在整个高中物理学习中.受力分析的基本步骤:1.明确研究对象——确定受力物体;2.隔离?
First, the force analysis of the balanced object The force analysis of the object is to find out the force that the selected object (ie the research object) receives in a specific physical scenario and draw a force diagram. Correct force is applied to the object. Analysis is the foundation for solving mechanical problems, and the stress analysis ideology is also permeated throughout high school physics learning. The basic steps of force analysis are as follows: 1. Define the research object—determine the stressed object; 2. Isolate?
