一、压力和压强压力是两物体间由于相互挤压而产生的垂直作用在物体表面上的力.压力不是重力,压力的大小有时与重力有关,但不一定相等.压强是物体单位面积上所受到的压力,压强公式P=F/S普遍适用于固体、液体、气体.二、液体的压强液体内部的压强产生的原因是:液体受到重力的作用,计算公式P=ρgh,(ρ为液体的密度,h为液体的深度),液体压强的大小与液体的重量、体积,及容器的大
1. Pressure and Pressure Pressure is the force acting perpendicularly on the surface of an object due to mutual extrusion between two objects. The pressure is not the force of gravity. The pressure is sometimes related to the gravity, but not necessarily equal. The pressure is the unit area of the object. Pressure, pressure formula P = F / S is generally applicable to solids, liquids, gases. Second, the pressure of the liquid The reason for the pressure inside the liquid is: the liquid by gravity, the formula P = ρgh, (ρ is liquid The density, h is the depth of the liquid), the liquid pressure and the liquid’s weight, volume, and the size of the container
