| Fluid | Any material that takes the shape of its container (Liquids and Gases) |
| Pressure | Force / Area |
| Buoyant force | The upward force that all fluids exert on matter |
| Buoyancy | The ability of a fluid to exert an upward force on an object immersed in it |
| Archimedes’ principle | The buoyant force on an object is equal to the weight of the fluid displaced by an object |
| Pascal’s principle | The pressure applied to a fluid is transmitted equally and unchanged throughout the fluid |
| Hydraulics | The science of applying Pascal’s principle |
| Bernoulli’s Principle | As the speed of a moving fluid increases, its pressure decreases |
| Boyle’s Law | If you decrease the volume of a container of gas and hold the temperature constant, the pressure will increase, or vice versa |
| Charles’s Law | The volume of a gas increases with increasing temperature, as long as the pressure on the gas does not change |
| Viscosity | Resistance to flowing |
