The Properties of Air
This property means air occupies space.
What is: Air takes up space?
The gas that makes up 78% of air.
What is: Nitrogen?
Gravity is described as this type of interaction.
What is: A force?
This principle states moving air creates lower pressure.
What is: Bernoulli’s Principle?
One of the four forces that pushes a plane forward.
What is: Thrust?
This property explains that air has measurable mass.
What is: Air has weight?
The gas that makes up 21% of air.
What is: Oxygen?
This force must be overcome for an object to fly.
What is: Gravity?
When air moves faster, pressure becomes ______.
What is: Lower?
This force slows an object moving through air.
What is: Drag?
This property describes air being squeezed into a smaller volume.
What is: Air can be compressed?
When air is heated, molecules do this.
What is: Move faster and spread apart?
This force causes objects to rise.
What is: Lift?
Blowing across paper causes it to rise because of this force.
What is: Lift?
Name one of the four forces of flight besides thrust and drag.
What is: Lift or Gravity?
This property allows air to slow heat transfer.
Air can insulate?
This happens to cooled air molecules.
What is: They slow down and move closer together?
Gravity depends on this property of objects.
What is: Mass?
Air is considered this type of substance in physics.
What is: A fluid?
Stable flight happens when forces are this.
What is: Balanced?
This happens to air when it is heated and molecules spread out.
What is: Air expands?
Heated air rises because it is less ______ than cooler air.
What is: Dense?
This principle explains why air moving faster over a wing creates lift.
What is: Bernoulli’s Principle?
Air moving over a wing faster than below creates this result.
What is: Lift due to pressure difference?
These are the three movements of an airplane.
What are: Pitch, roll, and yaw?
