Pressure Class 10| SEE Physics Notes Pressure: The pressure is the force applied on a per unit area. Formula of Pressure (P)= Force(F)/Area(A) P= F/A Unit of Pressure= Force(F)/Area(A)= F/m²= pascal(pa). Pascal(P): P= F/A= 1N/1m²= 1/1 = 1pascal The 1 pascal is the pressure when 1N force is applied at 1m². Atmospheric Pressure: The pressure exerted […]
