This explain why liquid perfume will come out of the nozzle fast when drawn up from the bottom of the bottle
What is the reduction of pressure from high to low?
100
The pressure applied equally in all directions in a fluid is called this
What is Pascal's Principle?
100
A plastic bag weighs 9 newtons. It rises back to the surface when pushed down because the buoyant force is this compared to the weight of displaced water
What is greater than displaced water?
200
Pressure typically acts on these 2 main states of matter
What is a gas and liquid?
200
This is done to cruise ships to reduce their density in water
What is shaping them to be hollow?
200
Heavy weighted jets create more of this with short wings?
What is thrust?
200
The upward force of a fluid exerted on all matter
What is buoyant force?
200
A fish floats because the buoyant force compares to the weight of the fish in this way
What is they are equal?
300
The SI Unit for pressure is this
What is the Pascal?
300
This explains why most objects float in water easier than air
What is a greater density than water?
300
Planes with no engines need this in order to fly
What is long wings?
300
The weight of water displaced by an object that is equal to an object's weight is called this?
What is Archimedes' Principle?
300
A rock sinks to the floor of a pond because the weight of an object compares to the buoyant force in this way
What is sinking?
400
The pressure that involves the force of the air molecules exerted above is this
What is atmospheric pressure?
400
Helium balloons float in air, because this is reduced in the balloon to decrease its' density
What is reduce mass relative to volume?
400
Air is fastest on this part of a ping pong ball when it's placed on a hair dryer
What is the top of the ping pong ball?
400
The forward force produced by a plane's engine
What is thrust?
400
Air always moves through our lungs from this pressure to this pressure?
What is high pressure to low pressure?
500
This is the force of the water molecules acting above someone
What is water pressure?
500
Submarines do this in order to rise and sink in the water
What is take in and shoot out water?
500
Planes do this when they encounter turbulence
What is adjust the plane flaps?
500
The force that opposes or restricts motion is known as this
What is drag?
500
This affects how much pressure we feel in the ocean
