Chapter Eleven
| Question | Answer |
|---|---|
| pressure | is equal to the force exerted on a surface divided by the total area over which the force is exerted |
| pascal | unit of pressure per square meter (N/m squared) |
| fluid | is a material that can easily flow |
| barometer | instrument used to measure atmospheric pressure |
| density | mass per unit volume |
| buoyant force | liguids and gases exert an upward force that acts on a submerged object. It acts in the direction opposite to force of gravity |
| Archimedes' Principle | states that the buoyant force acting on a submerged object is eual to the weight of the volume of fluid displaced by the object. |
| Pascal Principle | states that pressure increases by the same amount throughout an enclosed odr confined fluid |
| Bernoulli's Principle | states that the faster a fluid moves, the less pressure the fluid exerts. The speed of a moving fluid increases the pressure exerted by the fluid decreases |
| lift | upward force |
| hydraulic system | uses liquids to transmit pressure and multiply force in a confined fluid. |
