功和能是物理学中的重要概念,能的转化和守恒定律是自然界里最普遍、最基本的客观规律,功是能量转化的量度关系是解决物理问题的重要途径,也是解决电磁学、热学等领域问题的重要依据,又是高考命题的热点和重点内容.为了适应高考的需求,本文将功能关系问题的四种常规解法分别探 Work and energy are important concepts in physics. The law of energy conversion and conservation is the most universal and basic objective law in nature. It is a measure of the transformation of energy. It is an important way to solve physical problems. It is also a solution to electromagnetics and thermals. The important basis for such issues in the field is the hot spot and key content of the college entrance examination proposition. In order to adapt to the needs of the college entrance examination, this article explores four conventional solutions to the functional relationship problem.
