What is produced by spinning the spaceship around its own axis with a certain frequency which can provide centripetal force equal to the force of gravity at that point?
Correct answer: B. Artificial gravity
- A. Weightlessness
- B. Artificial gravity
- C. Vacuum
- D. None of the above
Explanation
B is correct. By spinning the spaceship around its own axis with a certain frequency which can provide centripetal force equal to the force of gravity, we can produce artificial gravity which reduces the feeling of weightlessness.

About Gravitation
Newton’s law of universal gravitation relates the force between masses to their masses and separation, while gravitational field strength explains weight and orbital motion. The topic covers satellite velocity and period, escape ideas, weightlessness in free fall, and artificial gravity, which differs from ordinary gravitational attraction.
