用能量观点解决物理问题是高中物理教学的重点内容,《普通高中物理课程标准》的内容标准中明确提出的定理和定律有:动能定理、机械能守恒定律、热力学第一、二定律和能量守恒定律,其中涉及到的能量有动能、重力势能、弹性势能、电势能、电能、内能、能量的量子化和能级、核能等.由于内容多,关系复杂,加上能量本身的抽象性,使得学生学习起来存在不小的困难.不仅如此,不少老师或是资料书上还要额外补充其他的一些常见的“功能关系”.例如,在一篇题为《归纳功能关 Solving physical problems from the viewpoint of energy is the key content of high school physics teaching. The theorems and laws explicitly stated in the content standard of “Ordinary High School Physics Curriculum Standards” are: kinetic energy theorem, conservation law of mechanical energy, laws of conservation of first and second laws of thermodynamics and law of conservation of energy , Which involves the kinetic energy of kinetic energy, gravitational potential energy, elastic potential energy, potential energy, electric energy, internal energy, energy quantization and energy level, nuclear energy, etc .. Due to the content, the complex relationship, coupled with the energy itself abstraction, making Not only that, many teachers or information books but also an additional supplement to some of the other common “functional relationship.” For example, in an article entitled "inductive function off
