PRESENTATION OUTLINE
PRESSURE IN FLUIDS
- Fluid pressure depends on depth
- The greater the depth, the greater the pressure
- Fluids are liquids and gases: they take the shape of there containers and flow
- Fluids flow from high pressure to low pressure areas
- Pressure = force divided by area

DENSITY AND BUOYANCY
- Density is the ratio of mass In a substance D=m/v
- Sinking: an object will sink if it is more dense than the fluid is in cr if it Has greater weight than the buoyancy
- Floating- an object will float if it's less dense than the fluid it's in or is equal to the buoyancy force
