#1. The Center of Gravity (or Center of Mass) is the point at which:
#2. For an inherently stable rocket, which statement about the center of gravity (CG) and the center of pressure (CP) is true?
#3. The Center of Pressure (CP) of a rocket is generally defined as:
#4. What is the recommend “rule of thumb” relationship between Center of Gravity (CG) and Center of Pressure (CP) for a stable rocket?
#5. What is a good guideline for determining how much weight a rocket motor can safely lift?
#6. Which of the following can occur if your rocket’s nose cone is seated loosely in the body tube?
#7. A 2inch diameter rocket, loaded with its motor, has a Center of Gravity (CG) two inches behind the Center of Pressure (CP). Is this rocket likely to be stable?
#9. Your simulation program recommended an 8 second ejection delay for your rocket and the motor you plan to use. The simulation program assumed no winds
#10. How does Newton’s Third Law (To every action there is always an equal and opposite reaction) relate to how a rocket ascends under the power of its motor?
#11. If you wanted to move the CP to improve stability, you would do so by:
#12. Which is the weakest fin attachment method and, although it is popular with model rockets, might not be strong enough for high power rockets?
#13. To reduce the effect of drag on a rocket:
#14. Which of the motors listed below has the highest average thrust?
#15. Which is a possible unsafe consequence of using fin material that is too thin or weak for your rocket and the motor that you are using?
