将一块木块扔到水里,木块会漂浮在水面上,我们说木块受到了水的浮力.将一块石块扔到水里,石块会沉入水底,石块受到了水的浮力吗?浮力是怎样产生的?下面我们来了解这些问题.什么是浮力如图1甲所示,将一石块悬挂在弹簧测力计下端,此时弹簧测力计的示数等于石块所受的重力.当我们用手向上托石块时,会看到弹簧测力计的示数变小,如图1乙所 Throwing a piece of wood into the water, the piece of wood floats on the surface of the water, and we say that the piece of wood is buoyed by the water.A piece of stone is thrown into the water and the piece of stone sinks to the bottom and the piece of stone is buoyed by the water What is buoyancy is generated? Here we understand these issues. What is the buoyancy shown in Figure 1 A, the suspension of a stone in the spring force gauge at the bottom, then the spring force gauge is equal to the number of stones By gravity, when we hold the stones up by hand, we can see that the spring dynamometer shows a smaller number, as shown in Figure 1,
