Pressure is a scalar quantity. The pressure exerted by a fluid is the result of the interactions between the fluid’s particles and the surface with which those particles interact. The absolute pressure of a fluid at a given point is equal to the sum of a reference pressure, such as the atmospheric pressure, and the gauge pressure at that depth in the fluid. Pressure increases with depth in an incompressible fluid.

Understand how pressure varies with depth and acts in all directions, leading to the upward net force on submerged objects. This principle explains why objects float and is key to fluid displacement and the concept of buoyancy.
