AS 200 & LE200 Final Test Review

Where did flight by balloon first occur?

• China

• Japan

• France

• United States

What do you need for an object to fly?

• an engine

• gasoline

• wings

• a force to lift it

Which edge of an airfoil cuts through the air ahead?

• chord

• camber

• leading

• trailing

What did aircraft designers use to test models of new aircraft?

• airfoils

• wind tunnels

• chords

• cambers

How many wing shapes did the Wright brothers test in designing their successful 1902 glider?

• 2

• 20

• 100

• 200

What laws are fundamental to our understanding of flight today?

• Quest's Laws of Airlift

• Newton's Laws of Motion

• Paine's Laws of Force

• Wright's Laws of Flight

According to Newton's second law of motion, an object's acceleration is proportional to the sum of all forces exerted on it. How can you write this law?

• force (f) = mass(m) + acceleration (a) or F=m+a

• force (f) = acceleration(a) / mass(m) or F=a/m

• force(f) = mass(m) x acceleration(a) or F=ma

• force(f) = acceleration(a) - mass(m) or F=a-m

What does Newton's third law state?

• For every action there is an equal and opposite reaction

• For every reaction there is a natural occurring action

• For every force there is pressure

• For every action there is an undetermined reaction

According to Bernoulli's principle, when air flows over the curved upper surface of a wing, it ___________.

• slows down

• lifts

• speeds up

• drags

What changes the angle of attack on a plane's wings?

• knot

• pitch

• relative wind

• air pressure
