1. How did the height you estimated your rocket would reach compare with the actual
estimated height? My estimated height was 40 meters high, but it probably reached 20 meters. I think it was because of the low water levels reaching 20% water level but other rockets had 50% water level.
2. What do you think might have caused any differences in the height you achieved? Definitely the water percentage I had a really low water percent which was 20% when I was supposed to have 50% or higher. Another factor was the fins, the problem was I didn’t have any fins which can cause an imbalance and topple the rocket down.
3. Did your rocket launch straight up? If not, why do you think it veered off course? It launched straight but veered off a little when it turned. It was because it had no fins and also the weight was unbalanced.
4. Do you think that this activity was more rewarding to do alone? Would you have preferred to
do it in groups? Why or why not? I prefer it alone because it would be hard to work in groups, people would have different ideas and it would be less amusing on the launch date because there are fewer rockets.
5. Did you adjust your model rocket at all? How? Do you think this helped or hindered
your results? I did not adjust my rocket at all but if I were to, I would add fins and a better parachute mechanism.
6. How do you think the rocket would have behaved differently if it were launched in a
weightless atmosphere? It would gain height significantly, and continue upwards and slow down over time because of the air resistance. It would crash only if the rocket lost balance and turned 360 degrees and be propelled by thrust. I don’t think it would fall down because without weight there are no opposing forces (except drag).
7. What safety measures do you think engineers consider when launching a real rocket?
Consider the location of most launch sites as part of your answer. The engineers would go to a remote location and make sure spectators are so far away, that the smoke the rocket produces would not be able to reach the spectators. also, the launch pad would be heat resistant and the rocket would have to be designed well. I think they would launch somewhere where the location is near an ocean so that the rocket “cartridges” would land on the ocean instead of them landing on cities.
8. When engineers are designing a rocket which will carry people in addition to cargo, how
do you think the rocket will change in terms of structural design, functionality, and
features? It would be reusable, cost less, eco-friendly, less risk to the astronaut by increasing the durability and even make it more aerodynamic by reducing the size and weight.
9. Do you think rocket designs will change a great deal over the next ten years? How?
Yes, why? Because of SpaceX. Rockets will prioritize being more eco-friendly and reusable.
10. What tradeoffs do engineers have to make when considering the space/weight of fuel
vs. the weight of cargo? They have to make sure that the weight of the cargo will not counter the thrust force of the rocket engine. The less weight of the cargo means that there is less risk for the rocket not reaching the atmosphere.
