Define thrust and pressure and give their unit and dimensional formula.

(N/A) $(i)$ The force applied on a surface in a direction perpendicular to the surface is called thrust. Due to thrust,liquid flows out from the hole of a container.
$\rightarrow$ Thrust is a force. Its $SI$ unit is Newton $(N)$. Its dimensional formula is $[M^{1} L^{1} T^{-2}]$.
$(ii)$ Pressure: The force acting on a surface per unit area,in a direction perpendicular to it,is called pressure on the surface.
$\rightarrow$ If $F$ is the force acting perpendicular to the surface of area $A$,then pressure $P = \frac{F}{A}$.
$\rightarrow$ $SI$ unit of pressure is $\frac{N}{m^{2}}$ or Pascal $(Pa)$.
$\rightarrow$ $CGS$ unit of pressure is $\frac{\text{dyne}}{cm^{2}}$.
$\rightarrow$ Dimensional formula of pressure is $[M^{1} L^{-1} T^{-2}]$.
