1浮力探究实验利用弹簧的压缩长度跟受到的压力成正比的原本人制作了浮力显示器,如图1所示,当重物A受到图1图2向上的托力时,弹簧压缩,指针上移,箭头在刻度板指示出托力大小,当重物浸入液体时就能直接显示浮力.用两个完全相同的浮力显示器组成浮力探究(其中一个的刻度板背面设有 1 buoyancy exploration experiment using the spring compression length proportional to the pressure received by the original production of buoyancy display, shown in Figure 1, when the weight A by Figure 1 Figure 2 upward force, the spring compression, the pointer up , The arrow indicates the size of the torquing on the scale plate and the buoyancy force can be directly displayed when the weight is immersed in the liquid. Buoyancy is explored using two identical buoyancy displays (one on the back of the scale plate
