Pressure

The amount of force applied per unit area in a direction perpendicular to the surface of object is called as pressure.

Pressure
Force is directly proportional to the pressure and inversely proportional to the area.

Force as constant :

By putting force as constant, if area is less pressure is more and similarly if area is more pressure is less.

Area as constant :

By putting area as constant, if applied force is more pressure is more and similarly if applied force is less pressure is less.

Unit of pressure :

As we know the unit of force is newton (N) and the unit of area is (m2) 

Therefore the SI unit of pressure  is N/m2 which is also called pascal (pa).

                           1 pa = 1N/m2 

Pressure is a scalar quantity because it has no specific direction and has only magnitude.
