功、能概念、功和能的关系以及各种不同形式的能相互转化和守恒规律是自然界中最重要、最普遍、最基本的客观规律,是在牛顿运动定律的基础上,研究力和运动关系的进一步拓展,用能量观点分析问题,为解决力学问题开辟了一条新的途径。功和能的关系,能量的转化和守恒,往往出现在高考压轴题中从功能的角度来分析和解决物理问题往往显得非常简捷。学习物理必须加深对功能关系的理解和应用。下面介绍常见的几种功能关系;
The concepts of power, concept, work and energy, as well as various forms of mutual transformation and conservation laws are the most important, universal and basic objective laws in nature. They are based on Newton’s law of motion and study forces and movements Further expansion of the relationship, the analysis of the problem with the energy point of view, to solve the mechanics problem has opened up a new avenue. The relationship between power and energy, energy conversion and conservation, often appear in the college entrance examination pressure axis from the perspective of the function to analyze and solve the physical problems are often very simple. Learning physics must deepen understanding and application of functional relationships. The following describes several common functional relationships;
