7.1 Pressure
Pressure : Pressure is defined by the force acting per unit area.
P= F
A
S.I Unit Pascals (Pa)
7.2 Pressure in liquids
The earth's gravitational pull acts on all objects including liquids.
The amount if pressure inside a liquid body increases with depth.
Pasacal's principle: If pressure is applied to an enclosed liquid the pressure is equally transmitted to the other parts of the liquid.
The principle of conservation of energy applies in the hydraulic press.
The car hydraulic brake system allows to speed up,Slow down or Stop the car
The force applied by the driver multiplies when the area of piston increases.
