相对于文字表征和公式表征,函数图象往往更能直观地呈现出多个物理量之间的关系.图象法在物理学习和解决物理问题的过程中应用相当广泛,对于“物理实验”学习亦不能外.图象是对实验数据进行处理、对物理过程进行表征的重要工具,在实验试题中也经常以图象的形式来创设物理情境,提供相应的条件,并提出问题. Compared with text characterization and formula characterization, functional images tend to more intuitively show the relationship between multiple physical quantities.The image method is widely used in the process of physics learning and solving physical problems, and for “physical experiment” Learning is no exception.Image is an important tool for processing experimental data and characterizing the physical process. In the experimental questions, the physical situation is often created in the form of images, the corresponding conditions are provided and questions are raised.
