Effect produced due to force is more when the surface area is smaller and less when the surface area is larger.

One edge of drawing pin is flat while another is sharp

It is easier to cut with sharp knife rather

than blunt one.

Vertically placed brick soaks more in mud then horizontally placed

Force exerted on surface area on one unit is called Pressure. Pascal is the unit of Pressure.

Pressure = ------- Force

Area

Standstill Liquid and Gas exerts pressure

Pressure exerted on earth because of atmosphere is called Atmospheric Pressure

At sea level the atmospheric pressure is moreAs we go higher the pressure decreases. It becomes difficult to breathe as we climb higher.

Atmospheric pressure

Atmospheric Pressure changes according to time and place..Due to this difference in pressure, wind blows.
