Transcript of Chapter 13.1 Notes

Formula
- Formula: P = F/A ( Newtons/meters squared)

P is the pressure
F is the applied force
A is the surface area where the force is applied

For example, if you push on an object with your hand with a force of 20 pounds, and the area of your hand is 10 square inches, then the pressure you are exerting is 20 / 10 = 2 pounds per square inch.
Look at figures 3 and 4
- Figure 3 = pascal vase
- Figure 4= can crush experiment
Water: (liquid)
- As depth increases, pressure increases.
- Shape and area of container does not affect fluid pressure.
- Fluid pressure is determined by type of fluid and depth.
Pressure:
- The result of a force distributed over an area.
Pressure in fluids:
- fluid = takes the shape of its container
- liquids and gases are both fluids.
Chapter 13.1 Notes

FLUID PRESSURE

- Ex: a theatre seat vs bicycle seat (the theatre seat exerts less pressure and is more comfortable).
Ex: Pencil point and eraser

- A.K.A- PASCAL (SI unit of pressure)
- 1 KPA (kilopascal) = 1,000 Pa
1 N/m2 = 1 Pa


Water: (liquid)
- As depth increases, pressure increases.
- Shape and area of container does not affect fluid pressure.
- Fluid pressure is determined by type of fluid and depth.
Gas: (air)
- The weight of the Earth's atmosphere exerts a pressure of 101 KPA at sea level.
- Air pressure decreases as altitude increases.
