物理来源于生活,同时也应用于生活。初中生在这一阶段所要学习的物理知识包括:光学、力学、密度、压强、磁力等。这些知识可以解决很多我们现实生活中出现的现象,物理知识的学习可以让我们更好地去生活,并利用这些知识来创新,探究未知的领域,对我们的未来生活做出更多的贡献。那么在初中的物理教学中教师有着很多的苦恼,比如,学生学习物理知识的兴趣不高,课堂气氛 Physics comes from life, but also applies to life. Junior high school students at this stage to learn physics knowledge include: optics, mechanics, density, pressure, magnetism and so on. This knowledge can solve many phenomena that appear in our real life. Learning from the physical knowledge can make us better to live and make use of the knowledge to innovate, explore unknown areas and make more contributions to our future life. So in junior high school physics teaching teachers have a lot of distress, for example, students are less interested in learning physical knowledge, classroom atmosphere
