The SI unit of pressure is pascal (Pa) or force acting on a unit area (N/m2)
the largerthe force, the greater the pressure.
the larger the area, the smaller the pressure.
Liquids exert pressure due to their weight.
Liquid pressure increases with depth.
The air exerts pressure on us and the things around us. The pressure exerted by the atmosphere is called atmospheric pressure. Atmospheric pressure increases below sea level and decreases above sea level.
