所谓整体法,是对问题的整体结构或整个过程进行分析研究的方法,它不纠缠问题的细节,不着眼局部,而是将问题看成是一由相互联系的多种要素构成的整体,进而分析问题的整体结构或整个过程,从中得出解题途径的方法.笔者拜读了《物理教学》2010年6期第43页刊发《竖直方向的相对运动》一文,深受启发.就文中题1、题2的第(3)问原文作者从局部人手,分阶段对物理过程进行分析论证,思路清晰、逻辑严谨.美中不足之处在于,物理过程复杂,计算量大.本文就题1、题2的第(3)问从整体过程入手,运用
The so-called “whole law” is a method of analyzing and studying the overall structure or whole process of a problem. It does not tangle the details of the problem with its focus on the part but considers the problem as a whole consisting of a plurality of interrelated elements. Analysis of the overall structure of the problem or the whole process, from which to find ways to solve the problem.I read the “Physics Teaching” 2010Year6Pages on page 43 published “vertical movement of the relative” article, inspired by. Question 1, title 2 (3) asked the original author from the local manpower, stages of the physical process analysis and demonstration, clear thinking, logical rigor.The fly in the ointment is that the physical process is complex and computationally large.In this paper, the title 1, Question 2 (3) start from the overall process, the use of
