What causes a paper airplane to return to neutral when it tilts?
Dihedral angle
Tail design
Paper weight
Wing size
What is the role of dihedral angle in flight stability?
It increases speed
It reduces weight
It helps in balancing
It decreases lift
Which force opposes gravity to allow a paper airplane to fly?
Lift
Tension
Thrust
Drag
What principle was incorrectly believed to explain how lift works?
Pascal's Law
Coanda Effect
Bernoulli's Principle
Newton's Third Law
What effect correctly explains how airflow assists in lift?
Bernoulli's Principle
Coanda Effect
Newton's Third Law
Venturi Effect
What happens when the airflow follows the Coanda effect?
It decreases pressure
It stabilizes the plane
It follows the surface contour
It increases lift
What is 'wing loading'?
Weight of wings
Speed of wing flapping
Lift generated by wings
Weight divided by wing area
What is the main advantage of the Phoenix Lock design?
More weight
Enhanced color
Reduced drag
Increased speed
What makes the Super Canard design stall-resistant?
Low altitude
High speed
Heavy weight
Dual-wing configuration
Why is the Super Canard plane considered advanced?
Because of its size
Due to its dual wings
Because of its color
Due to its speed
How does the Tube Plane generate lift?
By flapping
With jet propulsion
Through spinning
Using a motor
What does a boundary layer do?
Slows down the plane
Helps in lift generation
Decreases lift
Increases drag
