复习力学时,在认真阅读教材、做好基本练习的基础上,适当解一些综合性较强的习题,对于全面认识力学现象,深入理解力学中的概念和规律,培养综合应用力学知识分析解决实际问题的能力,都有重要作用。一道综合题,往往涉及几个不同的力学过程连续发生变化,或在某一过程(或状态)中同时存在着几种力学现象。解答这类问题时,必须仔细分析题设现象的物理内容,判明其遵循的力学规律,弄清在这些现象中应考虑哪些物理量以及它们的联系;并要在列式求解中,注意检查解题步骤是否清楚,推理论证是否严密,所得结果是否合理等。
Reviewing mechanics, carefully reading the textbooks, basic exercises, based on the appropriate solution to some of the more comprehensive exercises, for a comprehensive understanding of mechanics, in-depth understanding of the concepts and laws of mechanics, to develop a comprehensive application of mechanics knowledge to solve practical problems The problem's ability has an important role. A comprehensive question often involves the continuous change of several different mechanical processes or the simultaneous existence of several mechanical phenomena in a certain process (or state). To solve such problems, we must carefully analyze the physical content of the phenomenon, identify the laws followed by their mechanics, to find out what physical quantities should be considered in these phenomena and their connection; and in the column solution, pay attention to check the problem-solving Whether the steps are clear, reasoning argument is tight, the results are reasonable and so on.
