笔者在多年的教学中发现,很多学生物理成绩难以拔尖的原因其实不在物理素质和水平方面,而在数学知识的运用方面,他们不会把学到的数学知识很好地运用到物理解题中去,而是把物理与数学分离开来.数理原本一家,学好数学是物理拔尖的基础,充分运用数学知识解答物理问题,是快捷解题夺得高分的手段.下面通过两个典型的例题,探讨物理问题中运用数学知识的一些技巧.例题1如图所示,在很大的水平地面上,某人站在离公
The author found in many years of teaching that many of the reasons why students’ physical achievements are not top-notch are actually not in the aspects of physical quality and level. However, they do not apply mathematical knowledge well to solving physical problems in the application of mathematical knowledge To go, but to separate the physics and mathematics. Mathematical origin, learn mathematics is the basis of physical top-notch, make full use of mathematical knowledge to solve physical problems, is a quick solution to the problem of winning high scores through the following two typical examples , To explore some of the skills in the use of mathematical knowledge in physics problems Example 1 As shown, on a large horizontal ground, someone standing away from the public
