Hello friends, today we will talk about this post about pressure.

What is pressure?

Pressure is a pressure, when it responds to anything, that work is done.  

Like when you hit the nail on your wall, until we do not put pressure on the nail.  So the nail does not fall on the wall, but as soon as we put pressure on the nail, the nail gets stuck in the wall.  This is called pressure.

The SI unit of pressure is pascal (Pa)

Formula-.    

                       P=F/A.     

P= Pressure

F= Force

A= Area
