Question

The force acting on unit area of a surface is called ___________.

Answer 1

1. The force acting on a unit area of an object is called pressure. The pressure on a surface depends on the magnitude of the force acting perpendicular to the surface and the area of the surface.
2. The relation of pressure is:

$\text{Pressure}=\frac{\text{Force}}{\text{Area}}$

3. Unit of the pressure in the SI system is the pascal ($\text{Pa}$) or$\frac{\text{N}}{{\text{m}}^2}$.

Hence, the force acting on unit area of a surface is called pressure.
