Life is filled with ups and downs
It's all just push and pulls
It's a bird, it's a plane, it's...
Flying through the ages
100
The opposing forces that allows an object to go up or down in the air. You must say which does which.
What is: lift raises the object and weight pulls the object downwards.
100
The force that pulls the flying object backwards
What is drag?
100
What do insects and birds use to create lift when getting off the ground?
What is...they flap their wings.
100
The person who created the first airplane.
Who are the Wright Brothers.
200
What month of the year is Mrs. Rushton's dog's birthday?
200
What must be true for an object to maintain constant speed in flight that is level?.
What is thrust must equal drag
200
When a bird wants to turn in the air, they dip one wing down. If a plane wants to turn, what part of the plane moves (and how)?
What is the Rudder (moves in the direction of the turn)
200
What are 3 items that were used to help hunt, that used the knowledge of the 4 forces of flight?
-fishing spears, bow and arrow, slingshot, (or other approved ideas).
300
Describe the shape of the airfoil that allows a flying object to lift into the air.
What is: a tear drop shape where the front (where the air hits it) is rounded.
300
Give an example of thrust in nature
What is ...a bird flapping its wings (or another approved answer).
300
Define air wake, and describe the shape that provides the least amount of air resistance (and smallest air wake).
What is: air wake is the difference in air pressure in front and behind of the moving object.
Smallest air wake come from a tear-drop shaped object
300
A traditional flying machine that has no propeller and no wings.
What is a hot air balloon.
400
Explain Bernouli's principle
What is...faster air moves over the top of the wing, (which spreads out the air particles and makes it less dense), and slower air under the wing (which makes it more dense). The more dense air pushes into the less dense air, which causes lift.
400
An example of something that provides thrust to a non-living flying object...that is not a paper airplane
What is...pulling back on a bow string to make an arrow fly (or another approved idea).
400
The reason why birds tuck their wings against their body when diving.
What is...it reduces their drag (more streamlined because less air friction) and increases speed
400
What type of specific science did Mrs. Rushton used to teach in High School (there are 2).
500
The reason why parachutes cause objects to fall to the ground more slowly
What is: they increase drag, which slows the downward flying person down.
500
A logical example of a scenario when drag is greater than thrust
What is...the flight is happening on an incredibly windy day when the wind is pushing against the flying object.
500
Why is it helpful for engineers to study air wakes and drag when designing airplanes
What is...to reduce fuel usage and create faster airplanes.
500
In the past, airplanes gained thrust with the help of ________, but now, most get thrust from_________________.
What is propellers. Then Jet Engines.
