学生在分析物理现象或处理物理问题时,常常出现错误的判断或者束手无策,原因主要是由于没有正确理解物理概念。如何正确理解物理概念呢?一、明确概念的分类初中阶段的物理概念可分为以下几种类型:1.反映物质属性的。如:运动、惯性、质量、能量、电、磁等,这类概念的特点是:其含义深刻,富有哲理性,很难从其表面定义上获得深入理解。只有随着知识的积累和发展才能由表及里、由浅入深地加深对概念的理解。以惯性为例:物体保持匀速直线运动状
When analyzing physical phenomena or dealing with physical problems, students often make erroneous judgments or are at a loss what to do because the physical concepts are not correctly understood. How to correctly understand the concept of physics? First, a clear concept of the classification of junior high school physics concepts can be divided into the following types: 1. Reflect the material properties. Such as: movement, inertia, quality, energy, electricity, magnetism, etc., these concepts are characterized by: its profound meaning, philosophical, it is difficult to get a deep understanding of its surface definition. Only with the accumulation and development of knowledge can we improve our understanding of concepts from shallow to deep. To inertia as an example: the object to maintain uniform linear motion
