压强公式p=F/S和p=ρgh是初中物理中两个重要的力学公式,两者的适用范围不同,前者对固体,液体和气体是普遍适用的,而后者仅适用求液体内部压强,但两者又是紧密联系
The pressure formulas p = F / S and p = ρgh are two important mechanical formulas in junior middle school physics. The scope of application of the two is different. The former is generally applicable to solid, liquid and gas while the latter is only applicable to the internal pressure of liquid, But the two are closely linked
