Physics / Pressure

Pressure is force per unit area applied in a direction perpendicular to the surface of an object.The perpendicular force acting on a surface is called thrust. Pressure =force/area SI unit:Pascal, denoted by Pa
Learn about pressure exerted by a liquid and its applications.Total pressure in a liquid of density d at a depth h = Atmospheric pressure + pressure due to liquid column = p + hdg
Understand the transmission of liquid pressure by Pascal's law - It states taht the pressure exerted anywhere in a confined liquid is transmitted equally and undiminished in all directions throughout the liquid.Find the applications of Pascal's law in hydraulic machine,hydraulic brakes,hydraulic jack.
Understand the concept of atmospheric pressure .Atmospheric pressure on the earth surface is the thrust exerted on unit area of earth surface due to column of air.The common consequences of atmospheric pressure - sucking a drink with a straw,filling a syringe with a liquid ,action of rubber suckers.Find out your own examples related to atmosheric pressure.Study about barometer and its uses.
