  1. Pressure

  2. ForceArea Pressure = B A Which block puts more FORCE on the surface? Which block puts more PRESSURE on the surface?

  3. The “deeper” you go,the greater the pressure. Pressure Pressure

  5. How does this picture illustratepressure as a function of depth?

  6. Why does the greater density, have the greater the pressure? ForceArea ForceArea Pressure Pressure

  7. = Pressure ForceArea = Height Area Mass·GravityArea = MassVolume Density ≡ (Density·Volume)·GravityArea = Density·(Area·Height)·GravityArea = Force = mass·gravity Force Mass Volume = Density·Gravity·Height Pressure = ρ·g·h

  8. Pressure = ρ·g·h ms2 kgm3 kgm·s2 m Pascals = = ρ = Density kg/m3 g = acceleration of gravitym/s2 h = height (depth)meters

  9. This is too much,I can’t handle the ρ·g·h!

  24. Pressure = ρ·g·h http://oak.cats.ohiou.edu/~bw249495/Hoover%20Dam%20-%20Arial.JPG

  25. Pressure = ρ·g·h

  26. P = ρ·g·h Pressure

  27. P = ρ·g·h Pressure

  28. P = ρ·g·h height http://www.jimharvey.org/2001/palmsprings/pump.html
