通过高中数学导数知识的学习,强化了学生的数学能力,丰富了物理问题解决的途径。本文阐释了导数本质、几何意义、物理意义,并应用求导的数学工具,简单明了、形象直观地探讨一些物理现象和实例,总结物理学中变化率问题的处理思路,这有益于高三复习中的数理学科综合,有益于培养学生应用数学知识解决物理问题的能力。 By learning high school math derivative knowledge, it strengthens students’ math ability and enriches the way of solving physical problems. This paper explains the essential, geometric meaning and the physical meaning of the derivative, and applies the mathematical tools of derivation. It simply and vividly discusses some physical phenomena and examples and summarizes the treatment ideas of the rate of change in physics, which is beneficial to the third year of the senior high school The synthesis of mathematical disciplines is conducive to students’ ability to apply mathematical knowledge to solve physical problems.
