Pressure of solids, liquids and gases
Terms, formulas, and interactive labs: sliders for the force and the area of support give the pressure and the graph p(S) is a hyperbola; a vessel with a choice of liquid and depth gives the pressure ρgh and the graph p(h); a hydraulic press with sliders for the piston areas and the force gives the force on the large piston; Torricelli's tube with sliders for the pressure and the height above the surface gives the height of the mercury column and the graph p(H); a body in a liquid with a choice of material, liquid and volume shows whether it sinks or floats and gives the Archimedes force and the graph F_A(V_sub).
Pressure of solids
Pressure, its unit the pascal, how pressure depends on the force and the area of support, ways to increase and to decrease pressure.
Pressure in a liquid. Pascal's law. Communicating vessels
Pascal's law, hydrostatic pressure $p = \rho g h$, why it does not depend on the shape of the vessel, communicating vessels.
Hydraulic press
How a hydraulic press works, the gain in force $F_2 / F_1 = S_2 / S_1$ as a consequence of Pascal's law.
Atmospheric pressure
Atmospheric pressure, Torricelli's experiment, the barometer, normal atmospheric pressure of $760$ mm Hg, how the pressure changes with height.
Archimedes' law and floating of bodies
The buoyant (Archimedes) force $F_A = \rho_{\text{l}}\, g\, V_{\text{sub}}$, conditions for floating, the waterline and displacement.
