| Pressure | Force divided by area |
| Fluid | A substance that assumes the shape of its container |
| Pascal' Principle | A change in pressure at any point in the fluid is transmitted equally and unchanged in all directions |
| Hydraulic system | uses pressurized fluid acting on pistons of different sizes to change a force |
| Bernoulli's Principle | As the speed of the fluid increases, the pressure within the fluid decreases |
| Archimedes' Principle | The buoyant force on an object is equal to the weight of the fluid displaced by the object |
| Balanced forces acting on a neutrally buoyant object | Buoyant force and gravity |
| Density | The ratio of mass to volume |
| Buoyant force is less than weight | The object sinks |
| Buoyant force is equal to the weight | The object floats |
| SI units for pressure | Pascals |
| Units for stress (Titanic movie) | Pounds per square inch |
| Stress | Can have the same units as pressure |
| Airplane flaps | Controls lift and drag |
| Airplane rudder | Controls yaw |
| Airplane elevator | Controls pitch |
| Submarine ballast tanks | Controls submarine weight |
| One Pascal | One Newton per meter squared |
| ROV | Remotely operated vehicle |
| NOAA | National Oceanographic Atmospheric Administrationic |
| North Carolina | First in Flight |
| Ohio | Home of the Wight brothers |
| Oxygen | 21% in the atmossphere |
| Nitrogen | 78% in the amtmosspere |
| One millilitter | One cubic centimeter |
