中学生学习物理,常有死记硬背、乱套公式,碰到复杂和生疏的问题,就感到难于下手的现象。究其原因,主要是对于公式的物理意义一知半解;对于物理问题不善于用科学方法进行分析。为什么会有这种情况呢?这是值得我们探讨的问题。 物理学研究的对象是物理现象。人们通过观察和实验,抽象出物理概念,总结出物理定律。对这些概念和定律的定量描述就是物理公式。然后在此基础上发展成物理理论。
When students study physics, they often have rote learning and inflexible formulas. When they encounter complex and unfamiliar problems, they find it difficult to start. The reason for this is mainly the lack of understanding of the physical meaning of the formula; it is not good for the analysis of scientific problems using physical methods. Why is this happening? This is a question worthy of our discussion. The object of physics research is physical phenomena. Through observing and experimenting, people abstracted the concept of physics and summed up the laws of physics. The quantitative description of these concepts and laws is the physical formula. Then based on this, it develops into physical theory.
