In this Density and Pressure section of Physics we cover the topics listed in the table below, each topic has a written tutorial (which you can read on your screen, print to read or use a web reader), a video tutorial, revision notes, revision questions and supporting calculators which allow you to check your own computations and calculations.
|9.1||Fluids. Density of Fluids|
|9.2||Pressure. Solid Pressure|
|9.3||Liquid Pressure. Pascal's Principle|
|9.5||Buoyancy. Archimedes' Principle|
|9.7||Adhesive and Cohesive Forces. Surface Tension and Capillarity|
This section concerns concepts such as density, pressure in solids, liquids and gases, buoyancy, adhesive and cohesive forces, surface tension, etc. In addition, various units of pressure used in different situations and the operating principle of equipment used to measure any gas and specifically air pressure are explained. We finish by looking at mechanisms used in daily life such as hydraulic lifts (used in pistons) and U-tubes (used to determine the density of unknown liquids).
In addition to the Density and Pressure tutorials, we also provide online Density and Pressure Calculators which allow you to calculate specific Density and Pressure formula in support of the tutorials or to check and verify your own calculations in support of your homework, coursework or thesis.
The following Physics Calculators are provided in support of the Density and Pressure tutorials.
