通过物理复习,要想真正掌握好物理这门功课,在中考时能应付自如,必须要达到如下四个要求:概念要清,问题要明,解题要巧,变换要妙。简而言之要做到“清”“明”“巧”“妙”四个字。一、概念要清首先要知道物理概念的内涵与外延,在此基础上,同学们要注意相似物理概念的联系,初中物理的许多概念如速度、功率、密度等,在定义的时 Through physical review, in order to really grasp the physics of this homework, in the exam can cope with ease, we must meet the following four requirements: the concept should be clear, the problem should be solved, the problem should be clever, the transformation should be wonderful. In short, to do “clear ” “bright ” “clever ” “wonderful ” four words. First, the concept must first clear the meaning and extension of the concept of physics, on this basis, students should pay attention to the connection of similar physical concepts, many concepts of junior high school physics such as speed, power, density, etc., in the definition
