本文拟分析机械能守恒常见模型的特征,探讨一般的解题方法,并举例分析.一、单体模型例如物体沿光滑面下滑、物体自由下落、物体被轻绳连接做圆周运动等,属于单体模型.这里所谓的“单体”实际上是一种习惯的、不严格的说法,严格来说,遵循机械能守恒的是包括地球在内的物体系.1.方法总结机械能守恒定律的研究对象是单个物体(严格来说还应包括地球),可以用以下几种关系列式:
This article intends to analyze the characteristics of the common model of conservation of mechanical energy and to explore the general problem-solving methods and examples.Material models such as objects glide along the smooth surface, objects fall freely, the object is connected by the light rope to do circular motion, belonging to the monomer Model. “The so-called ” monomer "is actually a habitual, non-strict statement, strictly speaking, to follow the conservation of mechanical energy is the system of objects, including the Earth .1 method to summarize the law of conservation of mechanical energy The object is a single object (strictly speaking, the Earth should also be included), you can use the following relations:
