虽然物理题的题型多样,不同题型运用的处理方法又有侧重,但解物理题还是有一般规律的:(1)在弄清题意后,根据题中展现的物理情景,根据已知条件和所求问题来确定主要选用哪些物理规律来解决实际问题,这是做好物理题的前提;(2)在此基础上充分利用已有的数学知识得出正确的结论.在教学实践中发现:由于多种原因,不少初中学生在做习题时(特别是热学和电学部分),感到完成后一过程很困难.不能把数学知识运
Although the types of physical questions are diverse and the methods of dealing with different kinds of questions are focused, there are still general laws governing the solution of the physical problems: (1) After clarifying the questions, according to the physical scenarios presented in the questions, Conditions and the question asked to determine which of the major physical laws to solve practical problems, which is a good physical condition of the premise; (2) on this basis, make full use of existing mathematical knowledge to draw the correct conclusion in the teaching practice Findings: For many reasons, many junior high school students find it difficult to complete the course after they have done exercises (especially in the thermal and electrical fields)
