Neutral buoyancy
the condition when an object submerged in a fluid neither ascends nor descends because its density is equal to that of the fluid.
Viscosity
a measure of a fluids resistance to flowing.
Buoyancy
the tendency of an object to float when immersed in a fluid.
Bernoullis principle
the principle that states that the fluid pressure of a flowing fluid decreases as its speed increases.
Hydraulics
the branch of physics concerned with the forces within and work done by liquids.
Pascals principle
the principle that states that pressure applied to a fluid is transmitted throughout the fluid.
Archimedess principle
the principle that states that an immersed object displaces an amount of fluid equal to its volume and that the weight of the displaced fluid is equal to the buoyant force acting on the object.
Boyles Law
a gas law that the pressure and volume of a sample of gas at a constant temperature are inversely proportional.
Buoyant force
the upward force caused by the displacement of a fluid.
fluid
any substance that can flow
pressure
a measurement of the amount of force acting upon a unit area
pascal
