Flight
Bernoulli’s Principle says that when air moves faster…
pressure drops
Who were the first people to create the first controlled flight in a plane?
The Wright brothers
How many of Newton's laws of motion are there?
3
These are the four forces acting on a flying object.
What are drag, weight, lift, and thrust?
Name the Property:
Air particles move more quickly when heated
Air has temperature.
Why would airplanes have weight restrictions on how much a passenger can bring on a plane?
answers may differ
What is aerodynamics
The study of how air moves around things.
These two items provide thrust for a non-jet plane
What are an engine and propeller?
Airplane wings are designed so that…
faster-moving air creates a pressure difference on top
How was thrust created in the first human powered airplane (1977)?
By pedaling
What is the most aerodynamically efficient shape?
A teardrop or airfoil
Name the Property:
Air can be squeezed together.
Air can be compressed
Explain why race car drivers use a spoiler that is shaped like an upside down wing
To force the car to the ground.
What is Altitude
is a measure of the height of an object above ground level
These adjust drag on a plane
What are wing flaps?
A soccer player kicks the ball with spin. Why does the ball curve in the air?
Spinning changes the air speed and pressure around the ball
What type of aircraft was the Hindeburg, which crashed in New York in 1937.
Airship, or blimp
A paper airplane flies much farther when the wings are slightly tilted upward at the back (trailing edge up) compared to when the wings are flat. Why is that?
The tilted wings change the airflow over and under the wing
