understanding pressure basics and beyond
Start
key consepts
Presssure is the force applied over a certain area. It appears in everyday situations like air pressure,water pressure and pressure in machines. Understanding pressure helps explain how objects move,float,or withstand forces
Basic pressure :P=F/A
Pressure diff:
ΔP=pgΔh
Atmospheric Pressure:P=101,325pa
Pressure in liquids:P=pgh
FORMULAS
Total pressure in a liquid:P.total=P.atmospheric+pgh
Density formula: p=m/v
Hydraulic Pressure:F1/A1=F2/A2
Gas pressure PV=nRT
What is Pressure?
Pressure tells us how much force is applied on certain areaIf the same force is applied n a smaller are,the pressure becomes higher. If the force spreads over a large area,the pressure becomes lower. Formulas: P= F\A Examples: A sharp knife cuts better because it has a small area ,so pressure is high. A camels wide feet reduce pressure on sand so it does not sink.
+ info
FACTORS affecting pressure
1.ForceMore Forces means more pressure2.Area Smaller area means higher pressure largers area means lower pressure 3.Direction of force Pressure acts perpendiculer to the surface
Pressure in liquids
Liquids exert pressure because the particles psh against the walls of the container and anything inside the liquidKEY WORDS: Pressure increase depth. Pressure increases with density of the liquid. Pressure acts in all directions FORMULA: P= pgh p is density g is gravity h is depth EXAMPLES: A dam is thicker at the bottom because pressure is higher there
+ info
PRESSURE IN AIR
Air has weight,so it pushes down on everything around us,this creates air pressureKey points: Air pressure is highest at sea level Air pressure decreases as altitude increases Air pressure changes cause weather changes Standard atmospheric pressure is 101,325 Pa Example:mountain vs sea level
Why air pressure changes
Air becomes less dense at higher altitudes.Temperature changes effect pressure. Weather systems high pressure=clear skies low pressure=rain Examples: your ear "pop" in a airplane because pressure changes.
+ info
Comparing pressure in air vs liquids
Pressure in liquids:depends on depth and density direction:all directions Formula:P=pgh
pressure in airdepends on altitude and temperature directions:all directions
Synthesis and organization, the two pillars for presenting
hydraulic pressure
knife surface area
surface area
diver underwater liquid pressure

Conclusions
Summary
- Pressure = force/area
- Liquid pressure increases with depth and density
- Air pressure decreases with height
- Pressure explains many real life situations :weather,floating,sinking,hydraulics,cutting and etc
