Artificial gravity can be created in the space craft by:
Correct answer: B. Spinning it around its own axis
- A. Revolving it around the earth
- B. Spinning it around its own axis
- C. Increasing its velocity
- D. Decreasing its velocity
Explanation
B is a correct option. Centrifugal force due to rotation can simulate the effects of gravity. If a spacecraft is spinning around its own axis, the astronauts inside would experience a force pushing them toward the spacecraft's outer edges, simulating the feeling of gravity. This is similar to the artificial gravity seen in some sci-fi movies, like the spinning space station in "2001: A Space Odyssey."

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.
