匀变速直线运动是高中物理体系中的重要内容,其中的题型种类较多,且其与牛顿定律结合的动力学问题一直是高考中的一个重要必考考点和考试难点.不少学生解决这部分的题目时常束手无策.笔者认为解决这部分题目,首先要熟悉并理解该部分的基本公式和一些常用推论.同时,对于一题有多解时能优先选用一些简便高效的解题技巧进行解题.能做到以上的两点需要学生学习中能领悟解各类题型的本质,对知识的融会贯通,解题时处变不惊.笔者现将在平时教学中指导学生如何进行熟练解题的一些技巧归纳整理如下.
Even speed change linear motion is an important part of high school physics system, of which the types of questions are more, and its kinetics with Newton’s law has been an important entrance examination exam points and test difficult.Many students to solve this Part of the subject is often helpless.The author believes that to solve this part of the problem, we must first familiar with and understand the basic formulas of this part and some common inferences.At the same time, when there is more than one solution can give priority to use some simple and efficient problem-solving skills to solve the problem To achieve the above two points need to be able to comprehend the nature of the various types of questions learned by students, the mastery of knowledge, when the problem is resolved.I will now teach in the usual teaching how to solve some of the skills of skilled induction Finishing as follows.
