Section 2.7 Pressure
Pressure is defined as force per unit area. That is, a force acting over an area is a pressure, and when you multiply a pressure by the area that it acts over, you get a force.
\begin{equation*}
P = \frac{F}{A} \qquad \text{or} \qquad F = PA
\end{equation*}
Pressure is directly proportional to force and inversely proportional to the area over which it is applied.
