图像是描述物理过程,揭示物理规律,解决物理问题的重要方法之一。利用图像表示物理规律往往比用公式表达更加形象直观、简捷准确。日常教学中图像的灵活运用,有助于学生掌握物理规律,培养其形象思维及数形结合的思想,同时可以提高学生科学表达物理过程和灵活处理物理问题的能力。因此有必要让学生在高中阶段加深对图像的理解,学会利用图像巧妙地处理一些物理问题。
Image is one of the most important ways to describe physical processes, reveal physical laws and solve physical problems. The use of images to express the laws of physics tend to be more intuitive than the expression of formulas, simple and accurate. The flexible use of images in daily teaching helps students grasp the laws of physics, cultivate their thinking of combination of images and figures, and at the same time enhance students’ ability of expressing the physical processes scientifically and flexibly dealing with physical problems. Therefore, it is necessary for students to deepen their understanding of the image in high school and learn how to use the image to skillfully deal with some physical problems.
