Fluid
|
any material that can flow that takes the shape of its container.
|
|
|
Pressure
|
The amount of force exerted on a given area.
|
|
|
Pascal
|
The SI unit for pressure.
|
|
|
Atmospheric Pressure
|
The pressure caused by the weight of the atmosphere
|
|
|
Density
|
The amount of matter in a certain volume, or mass per unit volume.
|
|
|
Pascal's Principle
|
States that a change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of that fluid.
|
|
|
Buoyant Force
|
The upward force that fluids exert on all matter.
|
|
|
Archimedes' principle
|
States that the buoyant force on an object in a fluid is an upward force equal to the weight of the volume of fluid is an upward force equal to the weight of the volume of fluid that the object displaces
|
|
|
Bernoulli's Principle
|
States that as the speed of a moving fluid increases, its pressure decreases.
|
|
|
Bernoulli's Principle
|
States that as the speed of a moving fluid increases, its pressure decreases.
|
|
|
Lift
|
The increases pressure that results below the wing exerts an upward force. This upward force known as lift, pushes the wings upward against the downward pull of gravity.
|
|
|
Thrust
|
The forward force produced by the plane's engine.
|
|
|
Drag
|
The force that opposes or restricts motion in a fluid.
