Air and Aerodynamics Review

Match the parts of a plane with its function

• Generate Lift

• Rudder

• Generate Thrust

• Ailerons

• Change Roll (rotate body)

• Wing

• Change Yaw

• Vertical Stabilizer

• Control Yaw

• Jet Engine

What do we call the variable that we change in the experiment?

• Manipulated/ Independent Variable

• Controlled Variable

• Responding/ Dependent Variable

Which is NOT a property of air?

• Air expands when heated

• Air takes up space

• Air has mass

• Air is everywhere.

Answer explanation

Other properties are: air contracts when cooled, air can exist as a fluid, air can be compressed, and air exerts pressure!

According to Bernoulli's Principle, ​ ​ (a)   air creates ​ (b)   pressure and ​ (c)   air creates ​high pressure.

• fast
• low
• slow
• high

An airplane lifts because the air ​ (a)   the wing is moving faster and the air ​ (b)   the wing is moving ​ (c)  

• above
• below
• slower
• faster
• thrust
• drag

If lift is greater than mass/weight, the plane will

• Ascend

• Descend

• Go faster

• Go slower

If thrust is greater than the drag, the plane will

• Ascend

• Descend

• Go faster

• Go slower

If thrust is less than the drag, the plane will

• Ascend

• Descend

• Go faster

• Go slower
