Fluid statics

Buoyancy: Buoyancy refers to an upward force exerted by a fluid on an object immersed in it. It depends on the density difference between the object and fluid.

Pascal's Law: Pascal's law states that when pressure is applied to a confined fluid, it gets transmitted equally in all directions within that fluid.

Archimedes' Principle: Archimedes' principle states that an object submerged in a fluid experiences an upward buoyant force equal to the weight of displaced fluid.
