任何一门学科,如果没有一些概念作为分析、综合、判断、推理等逻辑思维的出发点,就不可能揭示这些学科的全部内容,也就失去了这门学科存在的价值。物理概念是反映客观事物本质的一种抽象知识。某一物理概念,就是某事物、现象的本质在人的大脑中的反映,它是在大量观察、实验,获得感觉、知觉,形成观念的基础上,通过分析、比较、综合、归纳、想象,区别出个别与一般、现象与本质,把一些事物的本质的、共同的特征集中起来加以概括而建立的。教学实践表明:要让学生学好物理,做到灵活运用物理知识处理问题,首先就得让学生掌握好最基础的物理概念。
Any subject can not reveal the whole contents of these disciplines without any concept as the starting point of logical thinking such as analysis, synthesis, judgment and reasoning, thus losing the value of this discipline. The concept of physics is an abstract knowledge that reflects the essence of objective things. A certain physical concept is the reflection of something and the nature of the phenomenon in the human brain. On the basis of a great deal of observation, experiment, feeling, perception and formation of ideas, through the analysis, comparison, synthesis, induction, imagination, Differentiate between individual and common, phenomena and essence, the essence of some things, common features set together to build up. Teaching practice shows that: For students to learn physics well and make use of the knowledge of physics to deal with problems flexibly, students must first master the most basic physical concepts.
