The force divided by the area on which it acts is called pressure.
Pressure =
SI unit of pressure is Pascal or newton per square meter .
CGS unit of pressure is Barye(Ba).
The smaller the area, the larger the pressure on a surface for the same force.
Cutting of vegetables and fruits is easy with the sharp end of the knife is due to the force acting on the sharp end is more as there is a low surface area.
It is easier to hammer a sharp nail into wood due to the force acting on the sharp end is more as there is low surface area.
The pressure exerted by this air is known as atmospheric pressure.
The barometer is an instrument used to measure atmospheric pressure.
