物理公式是物理概念、定律及原理的数学表达式,是物理学的精华.对物理公式,既要弄清其物理意义,又要知道其适用范围.在学习中,同学们如能对一些物理公式灵活变形,那么对于物理习题的解答、物理意义的理解,以及一些物理方法的掌握均会有所帮助.下面简述物理公式变形的两点用途. Physical formulas are mathematical expressions of physical concepts, laws, and principles. They are the essence of physics. For physical formulas, we must not only understand its physical meaning, but also its scope of application. In the course of study, students can learn about some physics. The formula is flexible and deformable, then the solution to the physical exercises, the understanding of the physical meaning, and the mastery of some physical methods will help. The following describes the two uses of the physical formula deformation.
