31 terms
Terms | Definitions |
|---|---|
 force | a push or pull |
| flow rate | the amount of fluid that flows in a given time |
| dynamic` | a system that involves movement |
| aerodynamics | the branch of mechanics that deals with the motion of gases (especially air) and their effects on bodies in the flow |
| hydrodynamics | The branch of mechanics that treats of the dynamics of fluids |
| kinetic molecular theory | the theory that all matter is composed of particles (atoms and molecules) moving constantly in random directions |
| melting | change from a solid to a liquid |
| evaporation | the change of a substance from a liquid to a gas |
| condensation | the process of changing from a gaseous to a liquid or solid state |
| solidification | Liquid to Solid |
| sublimation | a change directly from the solid to the gaseous state without becoming liquid |
| laminar flow | The movement of water particles in straight-line paths that are parallel to the channel. The water particles move downstream without mixing. |
| turbulent flow | water moving in an erratic fashion that can be characterized as a swirling motion |
| drag | resistance |
| streamline | to design smooth, rounded surfaces on an object so it slips through the air with the least possible resistance |
| viscosity | a liquid's resistance to flow |
| cohesion | attraction between molecules of the same substance |
| adhesion | the property of sticking together (as of glue and wood) or the joining of surfaces of different composition |
| surface tension | the result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together |
| viscometer | a measuring instrument for measuring viscosity |
| mass | the amount of something |
| weight | the amount of gravity pulling down on something |
| volume | measurement of the amount of space occupied by matter |
| meniscus | the curve at a liquid's surface by which you measure the volume of the liquid |
| displacement | the volume of a small irregular solid is measured through displacement |
| density | the amount of matter in a given space |
| buoyancy | the ability to float |
| Archimedes principal | states the buoyant force on any object is equal to the weight of liquid that the object displaces. |
| positive buoyancy | a characteristic of matter that makes it float |
| negative buoyancy | a charactersitic of matter that makes it sink |
| neutral buoyancy | a object that stays at the same spot you put it at; it neither sinks nor floats |
