论文部分内容阅读
高中物理从内容上可分为力学、热学、电磁学、光学、原子物理等部分,其中力学和电磁学两部分内容较多,占了总体的70％左右,尤其是力学部分,不但本身内容最多,而且体系较完整,并且它是学习整个物理学的基础,地位十分重要。一、受力分析是解决力学问题的基础对物体进行受力分析,是学习高中物理第一个需要掌握的基本功。受力分析,有两条不同的思维路径,下面分别加以论述: 1.根据力的性质和产生原因去进行受力分析。力是物体对物体的作用,物体间的作用产生原因不同,即
High school physics can be divided into mechanics, thermals, electromagnetism, optics, atomic physics and other parts from the content, in which the two parts of mechanics and electromagnetism are more, accounting for about 70% of the total, especially the mechanics, not only the content of its own , And the system is relatively complete, and it is the basis for learning the entire physics, the status is very important. First, the force analysis is the basis for solving the mechanical problems The force analysis of the object is the first basic skill that needs to be mastered to learn the physics of high school. Force analysis, there are two different ways of thinking, the following are discussed separately: 1. According to the nature of the force and the reasons for the force analysis. Force is the effect of an object on an object. The role of the object has different causes.
