“比较法”是学习物理知识的一种常用方法,它是通过对一些相近或相似的物理概念、物理公式、物理规律等的比较,找出它们的区别与联系,从而精准地掌握物理知识。“作用力与反作用力”广泛存在于发生相互作用的物体间,故掌握“作用力与反作用力”及其相关知识所遵循的规律,对于学好高中物理力学部分具有非常重要的意义。可运用比较的方法来研究“作用力与反作用力”的有关知识。
Comparative Law is a commonly used method to study physical knowledge. It is through the comparison of some similar or similar physical concepts, physical formulas, and physical laws to find out their differences and connections so that they can master the physical know how. “Force and reaction ” widely exist in the interaction between the objects, so to master “force and reaction force ” and its related knowledge follow the law, for learning high school physics and mechanics part has very important significance . The comparative method can be used to study the related knowledge of “force and reaction force”.
