| pressure | a force exerted over a certain area |
| hydraulic device | an instrument used to multiply force |
| Archimides' Principle | states that the buoyant force on an object is equal to the weight of the displaced fluid |
| buoyancy | the upward force that exists in a fluid due to the downward pull of gravity |
| Bernoulli's Principle | states that the pressure in a moving stream of fluid is less than the pressure of the surrounding fluid |
| density | the ratio of mass to volume |
| 1.0 | the density of water |
| fluid | liquids and gases are considered these |
| N per square cm | the unit for measuring pressure |
| gram per cubic cm | the unit for measuring density |
| high to low | fluids always move from |
| increases | as depth increases, pressure |
| displaces more water than it weighs | an object floats when it |
