1. What is the primary purpose of applying the Force-Velocity Model in a crash investigation?
- A. To establish the physical limits of the thrusters' performance.
- B. To create a detailed timeline of events leading up to the crash.
- C. To analyze the chemical composition of the materials used in the vehicle's construction.
- D. To determine the total financial liability for the incident.
2. Why is establishing a "maximum power" burn scenario crucial in the systematic evaluation of a crash?
- A. It determines the minimum fuel required for a safe landing.
- B. It sets a physical limit on what the thrusters can achieve on their own.
- C. It is the only scenario that the Force-Velocity Model can accurately simulate.
- D. It confirms the age and manufacturing date of the thruster system.
3. When using the Force-Velocity Model to investigate a crash, what key comparison is made?
- A. Comparing the cost of the thrusters to the total cost of the pod.
- B. Comparing the pilot's training record with the flight data recorder.
- C. Comparing the actual velocity change with the simulated maximum thruster capability.
- D. Comparing the pod's mass before and after the incident.
4. A space pod decelerated much faster than the Force-Velocity Model calculated for a "maximum power" thruster burn. What is the most logical conclusion for investigators?
- A. The thrusters were operating at a standard, expected level.
- B. The Force-Velocity Model is incorrect and should not be used.
- C. The thrusters must have malfunctioned and provided less force than expected.
- D. Another force, besides the thrusters, must have contributed to the deceleration.
5. In the context of a crash investigation, the Force-Velocity Model primarily serves to:
- A. Reconstruct the pilot's actions.
- B. Calculate the financial cost of the damage.
- C. Test the plausibility of different physical scenarios.
- D. Identify the location of the black box recorder.
6. In the scientific method, what is the primary role of a hypothesis?
- A. To provide a final, proven explanation for a phenomenon.
- B. To summarize all the data collected during an experiment.
- C. To serve as a testable, proposed explanation that guides an investigation.
- D. To establish a scientific law that is universally accepted.
7. A scientist observes that a plant in a dimly lit corner of a room is growing sideways towards a window. What is the most logical next step for the scientist?
- A. Immediately conclude that all plants need sunlight.
- B. Formulate a hypothesis about why the plant is growing that way.
- C. Write a final report on the plant's behavior.
- D. Measure the plant's final height and end the investigation.
8. Which of the following statements is the best example of a testable scientific hypothesis?
- A. Ice cream tastes better than frozen yogurt.
- B. If the temperature of water is increased, then it will take less time for sugar to dissolve in it.
- C. Space exploration is an important endeavor for humanity.
- D. Some birds are more beautiful than others.
9. An engineer notices a new drone model uses its battery 50% faster than predicted by design specifications. Which of the following is a valid hypothesis to explain this discrepancy?
- A. The drone's battery usage is higher than expected.
- B. The motors might be drawing more power than their rating suggests.
- C. The design specifications for battery life are incorrect.
- D. The drone should be redesigned with a larger battery.
10. What is the relationship between an observation and a hypothesis in a scientific investigation?
- A. A hypothesis is a summary of all observations.
- B. An observation is used to prove a hypothesis is true.
- C. A hypothesis is a proposed explanation for an observation.
- D. An observation and a hypothesis are the same thing.
