Buoyancy
Density
Bernoulli's Principle
Flight
Mixed Bag
100
An upward force that is exerted on object in the upward direction (this is found in water and other fluids and makes the object feel lighter)
What is Buoyant force
100
The amount of mass per unit of volume in an object (you can compare the measures of this in two different objects to determine whether it will float or sink in certain fluids)
What is Density
100
This states that the faster a fluid moves the less pressure it exerts
What is Bernoulli's Principle
100
an upward force (for bernoulli's principle it explains how plane's wings go upwards)
What is lift
100
The slower a fluid moves the pressure is
What is greater
200
this states that the buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces
What is Archimedes Principle
200
Mass divided by Volume (grams per centimeter cubed)
What is the Density Formula
200

By the air moving over the top of the chimney causes the smoke from the fire to

What is rise up

200
An airplane wing is designed so the air move at this speed above compare to the air below the wing.
What is faster
200
As you rise higher in the atmosphere the pressure
What is decreases
300
The two forces that act against eachother when an object is placed in a fuid.
What is gravity and buoyancy forces
300
the density of an object greater than the fluid it's placed in will have this reaction.
What is sink
300
Because this animal uses the pame principle as an airplane's wing
What is a bird
300
The friction an airplane experience when flying.
What is drag
300

An object in air has a weight of 9.8N on a spring scale in water it's weight is 7.8N on the spring scale because of this force

What is buoyant force

400

An object is dropped into a beaker containing a liquid. The object is suspended in the fluid showing this buoyancy.

What is neutral (Equal)  buoyancy

400
what is the density of water
What is 1g/cm^3
400
The air moves over the top of tube when the bulb is squeezed. This lowers the pressure at the top of the tube. The higher pressure at the bottom of the tube pushes the liquid up the tube.
What is an atomizer
400
The slower moving air under a planes wing when in flight changes the pressure this way causing the plane to lift
What is increase in pressure
400
A sphere made of steel is placed in water and floats because its center is filled with this fluid
What is air
500
If an object that floats on the surface displaces 8 cm^3 of water, the object then weighs
What is 8g
500
The density of an object would be changed by changing the object's mass or
What is volume
500
This on the back of a car acts in the oppsite way of an airplanes wing.
What is a spoiler
500

Air above an airplane wing is moving faster than the air below an airplane wing. This causes the plane to

What is increase its elevation
