Pressure (P) is defined as the force (F) applied per unit area (A) perpendicularly.
Pressure is measured in Pascal which is Newton per meter square.
Atmospheric pressure : The pressure exerted by air is called atmospheric pressure.
Liquid pressure : The pressure exerted by liquid is called liquid pressure.
Pressure = F/ A
F = m x g
liquid pressure (P) = d × g × h
