在物理教学中发现,同学们在应用公式解题时存在许多问题,主要表现在将公式用错,公式中各物理量写颠倒,乱套公式。这说明同学们对公式所表达的物理意义以及公式的适用范围似是而非,一知半解。物理公式固然很多,各公式的形式和内容也千差万别,学生学习或复习起来是比较困难的,但如果将物理公式归类分析学习,这对掌握 In physics teaching, students find that there are many problems in applying formulas to solve problems, mainly in formulating wrong formulas, writing inversions of physical quantities in formulas, and indiscriminately formulating formulas. This shows that the students’ physics and the range of formulas used by the formulas are plausible. Although there are many physical formulae, the form and content of each formula are also very different. It is more difficult for students to learn or review them. However, if the physical formulas are grouped and analyzed, this is a mastery.
