What is hydraulic system
100
The pressure difference between the top and bottom of the wing creates _______
What is lift
100
Buoyancy results in the apparent ______ of weight of an object in a fluid

100
Object is more dense than the fluid, object will ______
What is sink
200
SI unit for pressure=_______=_________
What is Pascal, 1n/m2
200
A change in pressure at any given point in a fluid is transmitted equally and unchanged in all directions throughout the fluid
What is Pascal's Principle
200
A racecar has an upside down wing that creates what?
What is downward force
200
An upward force that acts in the opposite direction of gravity
What is buoyant force
200
Density of object is equal to density of fluid, object will _______
What is suspend
300
Water pressure ________ as depth increases
What is increases
300
In a hydraulic system, force is ________, leading to an increased output force

300
As the speed of a fluid increases, the pressure within the fluid ________
What is decreases
300
States that the buoyant force on an object is equal to the weight of the fluid that is displaced
What is Archimedes' Principle
300
Why do boats float
What is they are shaped so that the weight of water that is displaced is equal to the weight of the boat
400
Air pressure at sea level

400
If the output piston is 10 times larger than the input piston, the output force will be _______ times greater than the input force
What is 10
400
Why do airplanes fly?
What is because the pressure above the wing is less than the pressure below the wing creating lift
400
The ability of a fluid to exert an upward force on an object placed in it
