Pressure, Pressure is defined as the force acting on a unit area of a surface. The effect of force is measured by this quantity., It can be represented as PRESSURE=FORCE/AREA, Pressure is directly proportional to force and inversly proportional to the area over which it is applied., So, if we decrease the amount of area, pressure increases and if we increase the amount of area, pressure decreases., Unit of pressure, The SI unit of pressure is Pascal..
