Four Forces
This force opposes weight and keeps an airplane in the air.
What is Lift?
This principle states that faster-moving air has lower pressure.
What is Bernoulli's Principle?
This is the main body of the airplane.
What is the fuselage?
These control roll.
What are ailerons?
This axis of motion is controlled by the elevator.
What is pitch?
This force is created by the propeller or jet engine.
What is Thrust?
According to Newton's Third Law, every action has this kind of reaction.
What is an equal and opposite reaction?
These generate most of the airplane's lift.
What are the wings?
This control surface keeps the airplane coordinated in turns.
What is the rudder?
This axis of motion is controlled by the rudder.
What is yaw?
This force slows an airplane as it moves through the air.
What is Drag?
The wing pushes this downward to help create lift.
What is Relative Wind (air)
These are used during taxi, takeoff, and landing.
What is the landing gear?
These help the wings produce more lift at lower speeds.
What are flaps?
This axis of motion is controlled by the ailerons.
What is roll?
If this force becomes greater than lift, the aircraft begins to descend.
What is Weight?
If thrust becomes greater than drag, the airplane does this.
What is Accelerate?
This airplane component creates thrust.
What is the propeller (or jet engine)?
This control surface produces lift for the tail.
What is the elevator?
During the paper airplane activity, cadets were instructed to use this method when making adjustments.
What is trial and error?
According to the lesson, constant speed requires thrust to equal this force.
What is Drag?
According to Newton's First Law, an object in motion stays in motion unless acted on by this.
What is an unbalanced force? (another force)
According to the lesson, the fuselage holds these two things.
What are passengers and cargo?
The pilot controls the airplane using these two cockpit controls.
What are the yoke and pedals?
According to the activity, after making changes, cadets tried to see whose airplane did this best.
What is flew the farthest?
