Artificial gravity can be supplied by which of the following ways so that normal force of gravity can be generated for the astronaut:
Correct answer: A. Rotating the space craft
- A. Rotating the space craft
- B. Back and forth motion spacecraft
- C. Up and down movement of spacecraft
- D. Keeping the space craft stationary
- E. All of the above
Explanation
In space, it is possible to create "artificial gravity" by spinning your spacecraft or space station. Technically, rotation produces the same effect as gravity because it produces a force (called the centrifugal force) just like gravity produces a force.

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.
