More questions about Moon Base Physics

These visible examples show the question style. LearnClash turns the full topic into ranked duels and spaced repetition.

1. 1 Easy

   How many times higher can a person jump at a moon base than on Earth?

   Answer: six

   Why: Suit and backpack weighed about 82 kg on Earth, and John Young's Apollo 16 jump salute rose only about 0.42 m.

2. 2 Medium

   What underground structures could protect Moon bases from radiation and meteors?

   Answer: lava tubes

   Why: Shaded floors of Moon pits stay near 17 C while the surface swings from 127 C to minus 173 C, and radar confirmed a cave under one in 2024.

3. 3 Hard

   How could moon bases store energy during the long night?

   Answer: regenerative fuel cells

   Why: By day solar power splits water; at night the gases recombine, storing over twice the energy per kilogram of space-grade batteries.

4. 4 Easy

   Why must moon base residents exercise several hours every day?

   Answer: muscle atrophy

   Why: Station crews already train an average of two hours a day, harnessed to a treadmill and mimicking weightlifting on a resistance machine.

5. 5 Medium

   How many Earth days long is the lunar day-night cycle for moon bases?

   Answer: 29.5

   Why: This 29.5 day cycle is the Sun returning to the same spot; the Moon orbits in 27.3 days, and each lunar night alone lasts about 14.75 days.

6. 6 Hard

   Why can we see about 59% of the lunar surface?

   Answer: libration

   Why: Libration in longitude reaches almost 8 degrees and in latitude nearly 7, letting Earth peek past all four lunar limbs.
