Pressure
- is FORCE per unit AREA
- measure of force
being applied to
the surface of
comething
- Force = Newtons
- Area = mxm OR
cmxcm
- P = F ÷ A
- Pressure = N/m2 N/cm2 Pa
- 1Pa = 1N/m2
- The same force
over a larger area
creates a smaller
pressure
- in Liquids and Gases
- at rest, pressure at
any point acts equally
in all directions
- pressure increases
with depth
- higher at bottom of
sea than at top
- Pressure difference = height x density x gravity
- Pressure = Pa
- Height = m
- Density = kg/m3
- Gravity = 10 N/kg (on earth)
