📚 Part 1: Multiple Choice

1. Which force acts upward on an airplane in steady flight?

Thrust

Drag

Lift

Weight

2. What is a main reason a wing produces lift?

Air moves faster over the top surface, lowering pressure

The wing pushes air down

The wing's angle of attack changes airflow

All of the above

3. If the angle of attack becomes too large, the wing may suddenly lose lift. This is called a:

Cruise

Glide

Stall

Slip

4. Which control surface primarily controls yaw (left/right nose movement)?

Ailerons

Elevators

Flaps

Rudder

✏️ Part 2: Short Answers & Activity

5. List the four main forces acting on an airplane in flight:

6. A glider has no engine. Explain in two sentences how a glider can stay in the air and travel forward.

7. Quick check with numbers: A small model plane at 15 m/s generates 20 N of lift. Its weight is 18 N. Will the model climb, sink, or stay level? Show a short explanation or calculation.

8. Creative drawing: Sketch the side view of a wing. Draw arrows to show airflow above and below the wing, label the high-pressure and low-pressure regions, and show the lift force with an arrow.
