物理学是研究物质运动规律的学科,而实际的物理现象和物理规律一般都是十分复杂的,涉及到许多因素。舍弃次要因素,抓住主要因素,从而突出客观事物的本质特征,这就叫构建物理模型。中学物理模型一般可分三类:物质模型、状态模型、过程模型。构建物理模型是一种研究问题的科学的思维方法。从本质上讲,分析和解答物理问题的过程,就是构建物理模型的过程。 Physics is a discipline that studies the law of motion of matter. Actual physical phenomena and physical laws are generally very complex, involving many factors. Abandon the secondary factors and seize the main factors to highlight the essential characteristics of objective things. This is called building a physical model. Physical models in middle schools can be generally divided into three categories: material models, state models, and process models. Building a physical model is a scientific way of thinking about the problem. In essence, the process of analyzing and solving physical problems is the process of building physical models.
