一、“F浮＝G物”的两种含义（1）物体悬浮的条件写作“F浮＝G物”，它表示浸没在液体中的物体受到向上的浮力与向下的重力正好平衡，物体可以停留在液体里任何深度的地方；这时V排＝V物，如图1所示．（2）物体漂浮的条件也写作“F浮＝G物”，它表示漂浮在液面上的物体受到向上 First, “F float = G material” two meanings (1) the condition of the object floating “F float = G object”, which means that the object immersed in the liquid is subject to the upward buoyancy and the downward gravity exactly balanced, the object Can stay at any depth in the liquid; at this time V row = V object, as shown in Figure 1. (2) The condition of the object floating is also written as “F float = G object”, which means that the object floating on the liquid surface is subject to upward
