浮力演示实验的系统探索简述如下:1、把一铁块挂在弹簧秤上,得一读数。浸没水中读数减小,读数差为铁块所受浮力。再测等体积橡皮泥所受浮力,可见两浮力相等。这说明同体积的不同物体浸没水中浮力相等。2、改变泥形再测,可见浮力大小不变,说明浮力 The systematic exploration of the buoyancy demonstration experiment is briefly described as follows: 1. Put a piece of iron on a spring scale to obtain a reading. Readings in immersion water are reduced and the difference in readings is the buoyancy of the iron block. Then the buoyancy of the equal volume of plasticine was measured, and the two buoyancy forces were equal. This shows that the same volume of different objects immersed in water equivalent to buoyancy. 2, change the mud shape and then test, we can see the same buoyancy, indicating buoyancy
