Viscosity | liquid's internal resistance or friction that keeps it from flowing. |
Buoyant Force | upward force that a fluid exerts on an object; opposite to the pull of gravity. |
Buoyancy | Tendancy of an object to float when playced in a fluid. |
Compressinility | extent to which a substance( solid, liquid, gas. ) can be compressed; objects under compression tend to deform in shape. |
Incompressible | Not capable of being compressed; liquids are said to be incompressible. |
Pressure | Messure of the amount of force applied to a givin area; as an equation: P=F over A ; where P+Pressure, F= Force, A= Area; messured in Pascals. |
Pascal's Law | When pressure is applied to liquid in a container, the pressure and force is transmitted equally and undiminished throughout the liquid; an elclosed liquid transmits pressure equally in all directions. |
Pump | Device that moves a fluid through or into something; Piston Pumps, Diaphram Pumps, And Archimedes Screws are 3 common kinds of pumps; The Heart is a natural pump. |
valves | Device that controls the flow of fluids. |
