Plain text

Pressure is an effect which occurs when a force is applied on a surface. Pressure is the amount of force acting on a unit area. Pressure is distinct from stress, as the former is the ratio of the component of force normal to a surface to the surface area. Stress is a tensor that relates the vector force to the vector area.

Latex

$p={\frac {dF}{dA}}$, where $dF$ is the force component perpendicular to the surface element of area $dA$.
