在物理学习过程中,很多同学都认为初中物理易学,高中物理比较难学.还有些教师把这一现象当作课题进行研究.其实初中物理是基础,初中物理与高中物理知识的联系是非常紧密的,分析与解决物理问题的思路与方法也是相同的.本文以一道常见的初中物理习题与2015年江苏高考物理试题第5题为例进行分析与说明,以期抛砖引玉.初中习题在一次工程爆破中,用一条96 cm长的导火线来使装在钻孔里的炸药爆炸,导火线燃烧速度是0.8 cm/s,操 In the process of physics study, many students think that junior middle school physics is easy to learn and high school physics is more difficult to learn, and some teachers regard this phenomenon as a subject to study .In fact, junior middle school physics is the foundation. The connection between junior high school physics and high school physics knowledge is very close Analysis and solution of the physical problems of the same ideas and methods.This article with a common junior high school physics exercises and the 2015 Jiangsu physical examination questions No. 5 as an example analysis and description, with a view to throwing bricks and stones .In junior high school exercises in a blasting , A 96 cm long fuse was used to cause explosives in the borehole to explode. The fuse burning rate was 0.8 cm / s
