P6 General Studies: Space Exploration and Aerospace Technology (Paper 2: intermediate)
Paper two adds conversions and orbital figures, turning km per second into km per hour.
Direct answers Remember one line: settle the units first, then put them into the formula.

03 Answers and one-line notes
| # | Answer | One-line note |
|---|---|---|
| 1 | About 40320 km per hour | 11.2 times 3600 gives 40320 km per hour. |
| 2 | About 24 hours | Its period matches Earth rotation, so it seems to hang at one spot in the sky. |
| 3 | The station and crew fall freely together, creating microgravity | It is not a lack of gravity but a shared free fall, so weight seems to vanish. |
| 4 | About 2.28 hundred million km | 1.52 times 1.5 gives 2.28 hundred million km. |
| 5 | About 40.1 trillion km | 4.24 times 9.46 gives about 40.1 trillion km. |
| 6 | About 42120 km | 7.8 times 90 times 60 gives 42120 km. |
| 7 | About 5339 km per hour | 384400 divided by 72 gives about 5339 km per hour. |
| 8 | To cut mass so the rest accelerates more easily | With the same thrust a lighter vehicle accelerates more, so empty tanks are dropped. |
| 9 | It is tilted about 98 degrees, so the planet rolls on its side | Most planets spin nearly upright, while Uranus lies almost on its side. |
| 10 | Gravity is still present; the crew and station fall freely together, which feels like weightlessness | In orbit gravity supplies the centripetal force, and the shared fall produces microgravity. |
04 What to do after marking
- After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
- Repeat the same item two days later; move to the next paper only when both attempts are correct.
- Parents only need the answer and note columns; there is no need to explain every item.
Then try paper three, which works through signal delay and orbital speed.Tutor Registration →
