2. AND IF A I R WEIGHT - GRAVITY DRAG THRUST LIFT
Bernoulli’s Principle demonstrates the relationship between air speed and pressure.
How / why does that relationship lead to lift?
KEY WORDS
1 OR 2
NOTES:
(Faster Air/Fluids = Less Pressure) (Over top = Lift)
AND IF
2. On the airfoil diagram located on the open response sheet:
a. Label: thrust, lift, weight, and drag, as they would affect the airfoil.
b. Show the direction of each force using arrows.
WEIGHT - GRAVITY A I R
DRAG
THRUST
LIFT

3. 3. Explain how an airplane and bird’s wings create lift.
AIRFOIL SHAPE – ANGLE OF ATTACK – THRUST (wings/engines)
4. Explain why must you wind the string toward the thin trailing edge of the wing for the rotor to lift?
AIR HIT ROUND / LEAD EDGE – ANGLE OF ATTACK – FASTER OVER
5. Objects that fly come in all different sizes/shapes. A rotor/wing can be heavy or light Explain what can/should be changed to allow for a heavier/larger object to fly just as high as a lighter/smaller one.
THRUST– STEEPER ANGLE OF ATTACK – SMOOTH
6. There are many advantages to mass produced items:
a. Identify at least one advantage of a mass produced item.
b. Why must the fishing line be custom made for each individual?
CHEAP – INTERCHANGEABLE– READILY AVAILABLE - UNIVERSAL
SHORT = THRUST – LONG = TANGLE
