物理知识在生活中得到广泛的应用,在日常生活中,有许多的例子,都与物理知识有着密不可分的联系。初中物理学本身的研究对象是声学、光学、热力学、电学和力学,它们都与人类的生活息息相关,本文以初中物理中的几个典型例子,对物理学与生活的联系做一个简单的分析。寻找实例,分析声音的产生与传播声音,与人类的生活息息相关,可以说在生活中声音无处不在,就连在安静的图书馆中,也会有一些轻微的声音,如同 Physical knowledge is widely used in life. In everyday life, there are many examples that are inextricably linked with the physical knowledge. The research object of junior middle school physics itself is acoustics, optics, thermodynamics, electricity and mechanics. All of them are closely related to human life. Based on a few typical examples of junior middle school physics, this article makes a simple analysis of the connection between physics and life. Looking for examples to analyze the sound production and dissemination of sound, is closely related to human life, can be said that in the life of sound everywhere, even in a quiet library, there will be some minor sounds, as
