| To find pressure,you must know | Force and area |
| One reason air pressure increases at lower altitudes is because a | There are more air particles in a given area |
| Fluids are | Either liquids or gases |
| The brake system on a car is an example of a (an) | Hydraulic device |
| When the area over which pressure is applied is increased, | The pressure decreases |
| The pressure in a moving stream of fluid | Is less than the pressure in the surrounding fluid |
| An airplane wing is designed to make the air move | Faster over the top than under the bottom |
| An object floats because it displaces a weight of fluid | Equal to or greater than its own weight. |
| Pressure is force divided by | area |
| According to____________principle, the buoyant force on an object is equal to the weight of the fluid displaced by that object. | Archimedes |
