对于解答浮力问题,一般有以下几种基本方法:1、压力差法。根据浮力产生的原因,用F浮=液体对物体上、下表面的压力差来解答规则形状的物体所受的浮力。2、公式法。利用阿基米德原理公式F浮=ρ液gV排进行计算。阿基米德原理普遍适用于一切浮力问题。3、差重法。利用物体在空气中 To solve the buoyancy problem, there are generally the following basic methods: 1, the pressure difference method. According to the reason of buoyancy, F floating = liquid pressure on the upper and lower surface of the object to solve the buoyancy of the object of the regular shape. 2, formula method. Use Archimedes’s formula F float = ρ liquid gV row to calculate. The Archimedes principle is universally applicable to all buoyancy problems. 3, differential method. Using objects in the air
