高中力学是高中物理的重要内容,既是重点,又是难点。在电学、磁学当中,难点也会落脚到力电结合上,只不过电磁学是模型,但难点仍然是力学。在高考中力学或力学与其他知识的结合所占的比例可达70%左右;高考的压轴题一般也是力学题,大多数的学生更是望而生畏。怎样才能处理好力学问题呢。经过我多年的摸索总结如下:一、什么样的研究对象力学的研究对象既可以是单个的物体,也可以整体或者说一个系统。一般来说整体作为研究对象,可以处理整体以外的物体对整体的
High school mechanics is an important part of high school physics, both the focus and the difficulty. In the electrical, magnetic, which will be difficult to fall into the power combined, but electromagnetics is a model, but the difficulty is still mechanics. In college entrance examination in mechanics or mechanics and other knowledge of the combination of up to about 70%; college entrance examination questions are generally mechanical problems, most students even more daunting. How can we handle the mechanics problem? After many years of groping summarized as follows: First, what kind of research object Mechanics of the object of study can be a single object, but also can be a whole or a system. Generally speaking, the whole object can deal with objects other than the whole to the whole
