Pressure is the ratio of force to the surface area over which it is exerted. Though solids exert pressure, the most interesting examples of pressure involve fluids—that is, gases and liquids—and in particular water and air. Pressure plays a number of important roles in daily life, among them its function in the operation of pumps and ...
What about solids? The simple expression for pressure as force divided by area leads to a bit of a confusion. Often teaching about pressure in schools starts with one solid resting on another. It might involve camels with big feet walking across the desert or stiletto heels being banned from the school hall.

As a scalar physical quantity (having magnitude but no direction), pressure is defined as the force per unit area applied perpendicular to the surface to which it is applied. Pressure can be expressed in a number of units depending on the context of use.
15.1: Pressure. Page ID. The pressure exerted by a force, →F, over a surface with area, A, is a scalar quantity, P, defined as: P = F ⊥ A. where F ⊥ is the component of the force perpendicular to the surface. The SI unit for pressure is the Pascal (Pa).
12 wrz 2022 · Solids are rigid and have specific shapes and definite volumes. The atoms or molecules in a solid are in close proximity to each other, and there is a significant force between these molecules. Solids will take a form determined by the nature of these forces between the molecules.
Dive into a comprehensive 42-minute physics lesson on density and pressure, part of a new chapter on Fluids and Solids. Explore the fundamental concepts of density, including its definition, formula, and SI units, with a focus on water's density and specific gravity calculations.
