1. G

Used to control a model rocket.

A. Weight

2. F

The faster the exhaust is pushed through the rocket engine, the more forceful this is.

B. Newton's First Law

3. D

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

C. Newton's Third Law

4. E

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

D. Drag

5. B

When weight and drag are in balance, this law explains why the rocket falls at a constant velocity.

E. Newton's Second Law

6. C

Rocket engines produce thrust through the application of this law.

F. Thrust

7. A

For a rocket to lift off, the thrust must be greater than this force.

G. Lift
