What is the name of either of two movable flaps on the wings of an airplane that can be used to control the plane's rolling and banking movements.
What are ailerons.
100
This pair of wing components is necessary to help the plane roll left or right
What are ailerons.
100
The ability to fly depends on opposing forces related to air pressure as described by this scientist's principle
Who is Bernoulli.
100
What do birds have that help them fly, other than wings?
(Either answer below is correct).
What are hollow bones.
What are strong pectoral muscles to generate thrust.
100
How would the airplane behave under the following conditions: 10 N Lift, 5 N Weight, 10 N Thrust, 2 N Drag....
What is ascending.
200
What is the turning movement of an airplane without rolling.
What is yaw.
200
When an airplane is taking off it is important to have these wing components extending down along the trailing edge of the wing to help increase aerofoil surface area and increase lift.
What are flaps.
200
Moving air over the top of an aerofoil goes faster than air moving over the bottom of the aerofoil creating a difference in pressure above and below the aerofoil resulting in this force...
What is lift.
200
These body parts provide birds with the necessary thrust for flight
What are pectoral muscles (chest muscles).
200
How would the airplane behave under the following condition: left aileron down, right aileron up
What is roll to the left.
300
What part of the tail controls the pitching of the nose of the airplane?
What are the elevators.
300
This movement must be controlled when rolling the plane left or right to prevent an uncontrolled vertical spin.
What is yaw.
300
According to Bernoulli's principle, moving fluids (like air) exert ______ pressure than fluids that are not moving or fluids that are moving more slowly.
What is 'less pressure'
300
The force that pushes against an object and reduces thrust.
What is drag.
300
How would the airplane behave under the following condition: shift + right arrow key
What is yaw right.
400
What is the name of the trailing edge of the wing that either increases or decreases drag by changing position.
What are flaps.
400
When flaps are extended during landing they increase this force to help the plane avoid crashing at slower speeds.
What is lift.
400
When the force of gravity is greater than the lift force, then the airplane behaves in this way...
What is descend or move to a lower elevation.
400
The force that counters lift while pulling all objects toward the centre of the Earth.
What is gravity.
400
Flaps are raised right before the wheels touch the ground to reduce lift. Raised flaps make air molecules passing over the top of the wing to...
What is slow down.
500
What is the resulting movement of the nose of the airplane when the tail rudder moves to the right
What is yaw to the right
500
When elevators are raised, the angle of attack reduces, so the airplane requires more thrust to maintain the same lift force while the nose does this...
What is lower (drop).
500
If the force of gravity is balanced with the lift force and the thrust is equal to the drag force, then what would the airplane be doing?
What is remain still (or not move on the runway).
500
The first organisms to fly on Earth.
What are insects. (No, birds were not the first species to fly on Earth).
