#1. Which shock cord material is common in model rockets, but not sufficiently strong enough to take the extra forces of deployment of larger, high-power rockets?
#2. What is the recommend “rule of thumb” relationship between Center of Gravity (CG) and Center of Pressure (CP) for a stable rocket?
#3. 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
#4. Two rockets are identical, except in weight: one weighs 2 pounds, and one weighs 3 pounds. Both are launched in the same conditions on the same type of motor. Which outcome would you expect to occur?
#5. 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?
#6. What is a good guideline for determining how much weight a rocket motor can safely lift?
#7. Two identical rockets are travelling at different speeds. Which rocket experiences greater aerodynamic drag force?
#8. Which forces are present during a rocket’s ascent and will negatively affect the altitude that the rocket achieves?
#9. When the CG is aft of the CP, the rocket will:
#10. Which method of recovery is not considered an active recovery method and is NOT likely to be safe for a high-power rocket?
#11. If you wanted to move the CP to improve stability, you would do so by:
#12. A 2inch diameter rocket, loaded with its motor, has a Center of Gravity (CG) ten inches forward of the Center of Pressure (CP). Which is most likely to occur?
#13. Which is the weakest fin attachment method and, although it is popular with model rockets, might not be strong enough for high power rockets?
#14. You can increase the stability margin of a rocket by:
#15. Your simulation program calculated that your rocket will achieve aerodynamic stability just before it leaves a 12-foot-tall launch rail. At the launch site, only 6-foot launch rails are available. You should:
