受力分析的方法和应用是物理学的基础,也是学习的难点和高考的重点,不少问题的处理有一些小技巧,灵活运用这些技巧,不但可以快速求解,还可节约大量的时间.本文就常用的方法作以归纳,供同学们复习时参考.一、受力分析的一般步骤解力学题,重要的一环是对物体进行受力分析.因物体间的作用是交互的,且任何一个力学问题都不可能只涉及一个物体,故解题时应根据题目的要求,将研究对象从系统中隔离出来,对它进行受力分析,必要时对相关的力进行平移,画一简图,才有利于问题的解决.
Methods and applications of force analysis are the basis of physics, but also the difficulty of learning and the focus of the college entrance examination, many problems dealing with some tips, flexible use of these skills, not only can be quickly solved, but also save a lot of time. Commonly used methods to be summarized for the students to review reference.A general analysis of the force to solve the problem, an important part of the force analysis of the object.Because the interaction between objects is interactive, and any A mechanical problem can not only involve an object, so the problem should be based on the requirements of the subject, the research object isolated from the system, its force analysis, if necessary, the relevant force translation, draw a simple diagram , Is conducive to the solution of the problem.
