1. G

This decreases when the spoilers are used.

A. Weight

2. F

The faster the air is pushed through the jet engine, the more forceful this is.

B. Newton's First Law

3. I

This, along with weight, acts as resistance to aircraft motion.

C. Vortices

4. E

If thrust is greater than drag, this law describes the increase in velocity.

D. Streamlines

5. B

When thrust and drag are in balance, this law explains why the aircraft has a constant velocity.

E. Newton's Second Law

6. H

Jets produce thrust through the application of this law.

F. Thrust

7. A

For an aircraft to fly, the lift must be greater than this force.

G. Lift

8. D

This is described as the flow of air along a smooth path.

H. Newton's Third Law

9. C

This swirling flow occurs near the wing tips.

I. Drag
