物理动态题是指物理过程复杂多变.没有固定模式的题型。这样题的训练.既有助于锻炼学生的应变性灵活性.又能提高解题能力。一、以理论知识为依据.分析物理过程.抓庄问题变化的原因。解答动态型题关键在于弄清问题的来龙去脉.掌握问题的内部联系。[例1]如图甲乙两个电路由已知电阻 R_1=40Ω The physics dynamic question refers to the complicated and varied physical process. There is no fixed pattern question type. This type of training will not only help students adapt to their flexibility, but also improve their ability to solve problems. First, based on theoretical knowledge. Analyze the physical process. Grasp the reasons for the changes in the village. The key to solving dynamic questions is to understand the ins and outs of the problem. Master the internal links of the problem. [Example 1] As shown in Figure A and B, the two circuits have a known resistance R_1=40Ω
