This is the amount of force exerted per unit area of a surface.
What is pressure?
100
This is the upward force that keeps an object immersed in or floating on a liquid.
What is buoyant force?
100
This is the reason why rocks, humans, and water do not float in the atmosphere.
What is they are more dense?
100
This is one thing that contributes to airplanes and birds ability to fly.
What is wing shape?
100
This is a force that opposes or restricts motion in a fluid.
What is drag?
200
These are the two states of matter that are considered fluids.
What are liquids and gases?
200
An object will sink in a fluid if this is greater than the buoyant force.
What is weight?
200
This is the one substance that is less dense than air.
What is helium?
200
This is how air moves over top of wings compared to the air moving below it.
What is faster?
200
This is what air crafts can experience when there is and irregular amount of drag.
What is turbulence?
300
This is the equation used to calculate pressure.
What is pressure = force / area?
300
In order for an object to float in a liquid, this must be equal to the objects weight.
What is the object's buoyant force?
300
This is the equation for density.
What is density = mass / volume?
300
This is an upward force on an object that moves through a fluid. It is caused by the slower air speed traveling underneath wings.
What is lift?
300
This is how an airplane can reduce the amount of turbulence it goes through.
What is changing the area or shape of its wings?
400
This is what happens to air pressure as you get higher in the atmosphere.
What is decreases or goes down?
400
This 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 that the object displaces.
What is Archimedes' principle?
400
These are the three ways you can change the overall density of an object.
What are shape, mass, and volume?
400
This is what determines the speed of a plane.
What is thrust?
400
This states that a fluid in equilibrium contained in a vessel exerts a pressure of equal intensity in all directions.
What is Pascal's principle?
500
This is what happens to water pressure the deeper you go down.
What is increases or goes up?
500
This is where fluid pressure exerts force on objects.
What is on all sides?
500
This would be how you would determine the buoyant forces acting on an object.
What is determine the weight of the volume of fluid displaced by the object?
500
This states that the pressure in a fluid decreases as the fluid's velocity increases.
What is Bernoulli's principle?
500
This is an example of Pascal's principle that displays how liquids can be used to create high amounts of force.
