Pressure is the amount of acting on a unit area.
It can be calculated using the P = F ÷ A.
The greater the force, the greater the acting.
The greater the area, the the pressure as the force is spread out over a bigger surface area.
Pressure is measured in N/m2 or (Pa).
The pressure in a fluid increases with , and decreases with height above sea level.
A can thus be used to measure height.
This instrument is known as an .
In a fluid, the pressure at a point acts equally in all .
Pressure can be through fluids.
This is made use of in car braking systems, industrial robots and steering.
