功和能的概念是物理学中重要的概念,是高中物理教学的重点内容之一,能量的转化和守恒定律是物理学的基本原理,在高中物理中的力学、热学、电磁学、光学和原子物理学中,都涉及一些需要用功能观点进行分析和解决的问题,由于这类问题有较高的思维起点,需要学生具有综合分析运用知识的能力,它完全符合理科命题思想--以能力测试为主导,考查考生 The concept of work and energy is an important concept in physics. It is one of the key contents of high school physics teaching. The law of energy conversion and conservation is the basic principle of physics. The mechanics, thermals, electromagnetics, and optics in high school physics are In atomic physics, there are some problems that need to be analyzed and solved with functional perspectives. Because these types of problems have a high starting point for thinking, students need to have the ability to comprehensively analyze and apply knowledge, which fully conforms to the scientific proposition idea--to ability Test-led, examine candidates
