It is the force applied on a particular area
We can say that
Pressure is Force acting on per unit of area
Formula of Pressure
How is Force, Area and Pressure Measured
Force is Measured in Newtons
Area is measured in Square Meters
Since Pressure is Force/Area,
It is measured in Newtons/Square Meters
Note 1
Since Pressure=Force/Area
If we decrease the amount of area,Pressure Increases
If we increase the amount of area,Pressure Decreases
Hence we can say that
- Smaller The Area More The Pressure
- Higher The Area Less The Pressure
Example of head of Nail
Head of nail does not enter into wood but pointed side goes into it
Reason
Head of nail does not enter into wood
It is because head of nail occupies more area and hence Pressure is Reduced
So,it is not able to exert enough pressure to go into the wood
Pointed Side Goes Inside Wood
It is because pointed size puts more pressure on small area
Hence,it is able to go inside wood
