Pressure exerted by solid

​

Force applied on a unit area is known as pressure. The standard international unit of measuring pressure is Pascals which is newton per meter(N/m2). Name pascal was given to the unit of pressure as a honor  of french mathematician   Blaise Pascal. 

​

Pressure = perpendicular force

                    Area

Pressure = F - N 

                A - m2

Pressure has a magnitude but no direction. Therefor pressure is scalar quantity.  Pressure increase when the surface area get decrease. We change the pressure in day to day life where it scenery, watch the following video about pressure.
