PRESENTATION OUTLINE
Pressure and Fluids
- Fluid pressure depends on depth.
- Greater the depth the greater the pressure.
- Fluids include liquids and gases: they take the shape of their containers and will flow.
- Fluids flow from high pressure to low pressure areas.
- Pressure is found by force divided by area.
Density and Buoyancy
- Density is the ratio of mass to volume in a given substance D=M/V
- Sinking: An object will sink if it is more dense that the fluid it is in OR if it has greater weight than the buoyant force.
- Floating: An object will float if it is less dense than the fluid it is in OR is equal to the buoyant force.
Archimedes Principle
- Displace to take place of.
- The principle states that the buoyant force in an object in a fluid is a upward force equal to the weight of the fluid it displaces.
