一般说来,综合试题涉及的物理知识较广,运用的物理概念和规律较多,解答的过程也较复杂.综合试题的形式是多种多样,如果按物理过程中规律运用的情况分,有分步综合和同步综合,本文就这两类综合题的解答思路分类浅析,并且以2005年的部分综合试题举例来说明.一、分步综合试题分步综合试题中的物理情景或过程是按时间先后顺序发生的,求解的方法是“分段法”;即先将物理过程划分为 n 个简单的阶段,弄清前一阶段与下一阶段的关系,再建立方程求解.例1(2005年广东物理卷) 如图1所示,半径为
In general, comprehensive examination of physics involves a wide range of topics, the use of more physical concepts and laws, the process of answering is also more complex.A comprehensive test questions in a variety of forms, according to the physical process of the use of law points, there are Step by step comprehensive and synchronous synthesis, this article on the two types of comprehensive analysis of the problem-solving ideas classification, and in 2005 some of the comprehensive test sample to illustrate.First, step-by-step comprehensive test questions in the step-by-step integrated physical scenario or process is According to the chronological order of occurrence, the solution method is “segmentation method”; that is, the first physical process is divided into n simple stages, to clarify the relationship between the previous stage and the next stage, and then establish equations to solve. 1 (2005 Guangdong physical volume) as shown in Figure 1, the radius is
