中学物理教学传授知识的任务,就是向学生讲清楚物理事实、物理概念、物理定律、物理理论。其中,物理概念是物理客体的概括、抽象、深化,揭示物质的某方面的属性。定律是概念间的联系,是以概念为基础的,而物理理论又是定律的概括。所以物理概念教学在物理教学中处于一个核心的环节,概念是最重要最基本的内容。物理量是“量度物质的属性的描述其运动状态时所用的各种量值”。因此在物理概念中有许多是物理量,如力、速度、电场强度、磁感应强度等,也有些不是物理量,如质点、平 The task of imparting knowledge in middle school physics teaching is to explain to students the physical facts, physical concepts, physical laws, and physical theories. Among them, the concept of physics is the generalization, abstraction, and deepening of physical objects, revealing the attributes of certain aspects of matter. The law is the connection between concepts. It is based on concepts, and physical theory is the generalization of laws. Therefore, the teaching of physical concepts is at the core of physics teaching. The concept is the most important and basic content. The physical quantity is “the various values ​​used to describe the properties of a substance in describing its state of motion.” So many physical concepts are physical quantities such as force, speed, electric field strength, magnetic induction intensity, and some are not physical quantities, such as particles, flat
