运用物理知识解决具体问题的关键,就是要会把问题中的实际物体(研究对象)和物理过程在具体的条件下抽象为怎样的模型.即明确把问题中的研究对象看作是什么样的理想化模型,把研究对象状态的变化看作是怎样的理想化过程.解决了建立物理模型问题,然后按照其遵循的规律列出方程,问题解决自然不在话下.一、确立研究对象,抽象出理想化的实体物理模型物理问题解决的基本思维方法是:确立研究对象,分析物理现象产生的物理过程,利用相应的物理概念和物理规律列出
The key to using physical knowledge to solve a specific problem is to abstract the problem of the actual object (object of study) and the physical process under specific conditions into what kind of model, that is, to clarify what the research object in the question looks like The idealized model regards the change of the state of the research object as the idealization process.It solves the problem of establishing the physical model and then lists the equations according to the laws it follows to solve the problem naturally.First, establish the research object, abstraction Out of the idealized physical model Physical problem solving basic thinking method is: to establish the research object, the physical process of analysis of physical phenomena, the use of the corresponding physical concepts and laws of physics
