Step 1 · Read the article

Open the article and read it at the level above. Then answer the questions below in your own words.

Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the principle of operation?Simulates gravitational force through centripetal acceleration in a rotating frame of reference
2. What is the primary justification?Mitigation of physiological deconditioning (bone loss, muscle atrophy) associated with prolonged weightlessness
3. How does spinning create artificial gravity?When a spaceship spins, the motion makes a force called centripetal acceleration push people toward the outer edge. This pushes them against the floor, so they feel weight, like gravity.
4. Why do astronauts need artificial gravity?Without gravity, astronauts can lose bone and muscle, and their hearts and blood can change. Artificial gravity helps keep their bodies healthy for long trips in space.

Centripetal Acceleration: The acceleration directed towards the center of a rotating object, necessary to maintain circular motion.
Microgravity: A condition in which the effects of gravity are very small, often experienced in orbit around Earth.
