100
For every action there is an equal and opposite reaction.
What is Newton's Third Law?
100
In straight-and-level, unaccelerated flight are four forces are ____________________
What is "equal in magnitude" or "balanced"?
100
In this theory of lift, air flows over the top and bottom of the airfoil and is deflected downward and the airfoil goes upward.
What is the Newtonian Theory or Newton's Third Law?
100
straight line that connects the leading edge to the trailing edge.
What is the chord?
100
The factor of an airfoil's lift that involves area of the wing exposed to the airflow.
What is the surface area of the airfoil?
200
Voyager 2 Satellite and how it will keep moving further and further away from Earth even though it doesn't have the ability to propel itself
What is an example of Newton's First Law of Motion (Inertia)?
200
The predominant forces of flight when considering a parachuting falling to the ground
What is drag and weight?
200
The theory of lift that best explains the Ping Pong Ball Demonstration and the Balloon demonstration.
Bernoulli's Theory
200
This asymmetrical airfoil does or does not have camber.
What is "does not" have camber?
200
The factors of an airfoil's lift that the pilot can change.
What is camber, airspeed and angle of attack?
300
A rocket's thrust goes forward while the rocket propellant goes backward is an example of which Newton's Law?
What is Newton's Third Law.
300
Has Both Magnitude and Direction
What is a vector?
300
Air is moving faster through this Venturi Tube, therefore the pressure in this area is________
What is "Lower"?
300
Angle between the leading edge and the relative wind flow
What is the angle of attack?
300
The pilot can fly at a lower altitude, but can not change this factor by themselves.
What can a pilot do to "change" the air density?
400
F = m x a
What is Newton's Second Law?
400
With a vector notation of <2,-5>, this vector moves in what two directions?
What is Right and Down (diagonally downward to the right)?
400
This theory of lift only shows that air flow is in contact with the bottom surface of the airfoil, which is why it is not a viable theory for lift.
What is "skipping stone" theory?
400
We call the front and the back portions of the airfoil, the front and back edges? True or False.
What is False? The edges of an airfoil are called the leading and trailing edges
400
The factor of an airfoil's lift that can be changed by descending in altitude.
What is the airspeed or air density?
500
What is a diagram of Newton's Third Law as it applies to an airfoil?
500
When a plane is climbing, it's propeller provides both __________ and ___________ forces of flight.
What are Lift and Thrust forces?
500
This theory of lift shows that air flow is only in contact with (and gets compressed against) the top surface of the airfoil, which is why it is not a viable theory for lift.
What is the Venturi Theory?
500
This type of aircraft's airfoil has thicker camber and is efficient (Is it an airliner, fighter jet or trainer?)
What is an airliner?
500
The pilot can increase lift and the camber by extending this control surface on the plane.
What are the flaps?
