Fluids
2
Density

• ? (rho), mass, and volume
• Density and Specific Gravity

The density of Iron is greater than that of
waterso why do (most) boats float? See Buoyancy
3
Pressure

• Pressure, Force, and Area
• ALL DIRECTIONS IN FLUIDS
• P?ghWhy?

Buoyancy

• Check this out!
• What is buoyant force?
• Example 10-7

Archimedes

• Weight of water displacedBuoyant Force!
• The quandary of a King
• Eureka! (Ive found it)
• How it works

8
Density vs. Buoyancy

• Displace more water with the same mass
• Get more Buoyant Force!
