物理是建立在实验基础上的一门自然科学。物理概念的形成是建立在实验现象的基础上,物理规律总是在实验探究中得到的。不仅物理概念的形成、规律的探究,离不开物理实验,而学生不易理解和接受的繁杂习题往往也需要实验演示和实验探究。通过实验现象让学生获得直观的感性认识,给理性认识提供基础,给问题的正确结论予以展示;通过对实验收集数据的分析和处理,让学生可以去伪存真,并从中发现问题,得 Physics is a natural science based on experimentation. The formation of the concept of physics is based on the experimental phenomena, the laws of physics are always obtained in the experimental exploration. Not only the formation of the concept of physics, the law of inquiry, can not be separated from the physical experiment, and students do not easily understand and accept the complicated exercises often require experimental demonstration and experimental exploration. Through the experimental phenomenon, the students get intuitive perceptual knowledge, to provide the basis for rational understanding, to the correct conclusion of the problem to be displayed; through the analysis and processing of experimental data collected, so that students can go to pseudo-true and find problems
