高中物理作为一门基础性学科,它是自然科学与现代科学的基础,发挥着极其重要的作用。在高中阶段,物理涉及的知识面广,如力学、电学、热学等,综合性较强。高中物理的极值问题是教学的重点和难点,极值问题在物理试题中频繁出现,既考查学生对物理知识的理解和掌握,又考查学生对数学知识的迁移能力。因此在高中物理课堂教学中,培养学生求极值的解题思路和解题方法十分关键,本文以常见题型为例,论述了高中物理求极值的几种方法。
High school physics as a basic discipline, it is the basis of natural science and modern science, plays an extremely important role. In high school, physics involves a wide range of knowledge, such as mechanics, electricity, heat, etc., comprehensive. The extremum problem of high school physics is the key point and the difficult point of teaching. The extremum problem appears frequently in the physical examination questions, which not only examines students ’comprehension and mastery of physical knowledge, but also examines students’ ability to migrate mathematics knowledge. Therefore, in high school physics classroom teaching, it is very important to train students to seek the extreme value of the problem-solving ideas and problem-solving methods. In this paper, taking the common type as an example, this paper discusses several methods of seeking the extreme value in high school physics.
