Air and Aerodynamics Check In 1

Type two vocabulary words that you can recall we have learned in Air and Aerodynamics so far.

Fire needs 3 things in order to burn. Heat, fuel and...

• water
• sand
• metal
• oxygen

Which of the following is NOT a property of air?

• Air does not have a fixed shape or volume

• Air has mass

• Air takes up space

• Air exerts pressure

Aircraft wings are shaped like what?

• Circular
• Square
• Airfoils
• Triangular

Which principle states that as the speed of air INCREASES, pressure DECREASES?

• Bernoulli's principle
• Einstein's principle
• Newton's principle
• Galileo's principle

In this picture, the air is moving:

• Faster over the top creating lower pressure. Slower on the bottom, creating drag

• Faster over the top creating higher pressue. Slower on the bottom creating lower pressure

• Faster over the top, creating lower pressure. Slower on the bottom, creating lift

• Slower on the top creating higher pressure. Faster on the bottom, creating thrust

In Aerodynamics, lift is defined as:

• The force that propels the airplane forward
• The force that pulls the airplane downward
• The force that stabilizes the airplane during flight
• The force that directly opposes the weight of an airplane and holds the airplane up in the air.

In Aerodynaimcs, thrust is:

• The force that slows down an object

• The force that steers an object left or right

• The force that propels an object forward

• The force that lifts an object off the ground

In Aerodynamics, Drag is:

• a force that propels an object forward through a fluid
• a force that acts opposite to the relative motion (slows down) of an object moving through a fluid

• a force that has no effect on the motion of an object through a fluid
• a force that only affects objects in space

In Aerodynamics, Weight is what?

• The amount of air resistance on an object
• The speed at which an object moves through the air
• Force exerted by the gravitational pull on an object
• The force exerted by the object on the air around it
