JROTC Science of Flight Lesson 1-3
Relative Wind Depends on an Aircraft's
Speed and Direction
What is Another Name for Newtons First Law of Motion
Inertia
In what Year Was the First Manned balloon flight
1783
At Approximately What Degree Does an Aircraft Reach its Critical Angle of Attack
About 15 Degrees
What Generates Most of an Airplanes Lift
Airfoils
Which 3 things Determine the magnitude of drag
An Aircraft's Speed shape, Speed, and the Air's Viscosity
Why does an airfoils Shape Generate Lift
As Fast Moving air rushes of the airfoil the Pressure Decreases, and the slower air cause a higher pressure under the wing causing lift
What does F= ma Mean
Force= Mass Times Ecceleration
What Can You do to Increase the Amount of lift
Increase The Angle Of attack
What's an example in aviation in newtons 3rd law of motion
Jet purpultion
Which Edge of The Airfoil is Rounded
Leading Edge
What Two Challenges does Weight Purpose in Flying
Overcoming the Aircraft's Weight and Controlling the Aircraft in the Air
What are the 2 Types of Drag
Parasite Drag, and Induced Drag
What is Aerodynamics
The Way an Object Moves Through the Air
What does a vertical and horizontal Stabilizer do
They keep the Aircraft stable
Why Must a Glider Have a Large Aspect Ratio
To reduce Drag
Which Edge of The Airfoil is Sharp
Trailing Edge
What Did the Wright Brothers Discover Using a Wind tunnel
Which Airfoil Produced the Most Lifting Force
