What is the definition of pressure in physics?

Pressure in physics is defined as the force exerted per unit area. It quantifies how much force is applied over a specific surface area, which can be critical in understanding various physical situations. For instance, in fluids, pressure describes how the force of gravity affects the fluid's weight distributed across a surface area.

In low-pressure systems, as seen in weather patterns, larger areas can experience less force, resulting in different environmental conditions. This concept is vital in engineering, meteorology, and numerous other fields. Thus, when defining pressure, it’s essential to recognize the relationship between force and area, which is encapsulated in the correct definition.
