高中物理总复习中狠抓基础,我认为应主要抓住基本物理概念,基本物理现象、基本物理规律和基本物理研究方法。现分述如下.一、基本物理概念对于每个基本物理概念,复习时应该使学生清楚地理解它的物理含义、大小的量度和单位的规定。如果是矢量,还要让学生明白它的方向是如何规定的。首先,物理概念一般都是为了描述某一客观物理现象而引入的.例如,“加速度”是为了描述机械运动速度改变的快慢程度而引入的;“电场强度”是为了描述电场的力的性质而引入的;电容器的“电容量”是为了描述电容器容纳电荷的本领而引入的等等。不少学生只满足于记忆物理概念的量度公式,而忽视
In the review of senior high school physics, I believe that the basic physical concepts, basic physical phenomena, basic physical laws, and basic physics research methods should be mainly grasped. It is described as follows. First, the basic physical concept For each basic physical concept, the review should enable students to clearly understand its physical meaning, size measurement, and unit regulations. If it is a vector, let the students understand how it is oriented. First of all, the physical concept is generally introduced to describe an objective physical phenomenon. For example, “acceleration” is introduced to describe how fast a mechanical movement speed changes; “electric field strength” is to describe the nature of the force of an electric field. Introduced; the “capacity” of a capacitor is introduced to describe the capacitor’s ability to hold charge, and so on. Many students are only satisfied with the formula of the memory physics concept and ignore
