求解物理习题,首先要感知题目所涉及到的物理现象,然后分析这些现象和过程,经过思维加工,严密推理,将结果准确地表达出来。直观性既是影响感知效果的重要因素,也是严密推理和表达的重要辅助手段。物理习题难点就在于,物理过程抽象或分析推理过程抽象,所以要运用直观图形手段化解物理难题。 To solve a physics problem, you first need to perceive the physical phenomena involved in the problem, then analyze these phenomena and processes, and then process them through thinking and rigorous reasoning to express the results accurately. Intuition is not only an important factor that influences the effect of perception, but also an important aid for rigorous reasoning and expression. The difficulty of physical exercises lies in the abstraction of the physical process or the analysis and reasoning process, so we must use intuitive graphics to solve the physical problems.
