初中物理教材中,对阿基米德原理表示式的说明:“浮力的大小只跟物体浸入的液体的密度和排开液体的体积有关,即只跟排开液体所受的重力有关,而跟其他因素无关。”学到这里,学生常常会有些想法,诸如浮力会不会跟物体的形状、密度、物体所受的重力以及容器中液体的总体积及其所受的重力等因素有关?为此,可以补充一些实验以消除学生可能的疑问。 In the junior high school physics textbook, the description of the Archimedean principle expression: “The size of the buoyancy is only related to the density of the liquid in which the object is immersed and the volume of the liquid to be discharged, that is, only related to the gravity received by the liquid, but with Other factors are irrelevant.” After learning this, students often have some ideas, such as whether the buoyancy will be related to the shape of the object, its density, the gravity of the object, the total volume of the liquid in the container, and the gravity of the container. Therefore, some experiments can be supplemented to eliminate students’ possible questions.
