Density and pressure
4.3What the syllabus asks of you
- define and use density
- define and use pressure
- derive, from the definitions of pressure and density, the equation for hydrostatic pressure ∆p = ρg∆h
- use the equation ∆p = ρg∆h
- understand that the upthrust acting on an object in a fluid is due to a difference in hydrostatic pressure
- calculate the upthrust acting on an object in a fluid using the equation F = ρgV (Archimedes’ principle)
