初中物理入门的学习中,比较方法的应用不胜枚举.通过比较而形成概念和掌握规律,例如:通过比较物体运动的快慢形成速度的概念;比较物体的冷热程度,建立温度概念;比较体积相同的不同物质的质量,并比较体积不同的同种物质的质量,则导致密度概念的建立.还有更复杂的例,例如:比较在 The introduction of junior high school physics learning, the application of comparative methods are numerous. By comparing the formation of the concept and master the law, for example: by comparing the speed of movement of objects to form the concept of speed; compare the level of hot and cold objects, the establishment of temperature concepts; compare the volume The same quality of different substances and the comparison of the masses of different substances of the same volume lead to the establishment of the concept of density, as well as more complex examples, for example:
