Question

Which of the following statements are true?
1 Earth'sgravity has no effect on astronauts inside the International SpaceStation. An astronaut's weight is the same on theMoon as on Earth.     Anastronaut's mass is the same on the International Space Station asit is on Earth. None of these statements are true.Anastronaut's mass is greater on Earth than on the Moon 1 Earth'sgravity has no effect on astronauts inside the International SpaceStation.

Explanation / Answer

1st statement is false because gravity extends to infinity(the effects of gravity are just not noticed by design tocounterbalance. Nonetheless, gravity does have an effect)
2nd statement is false; weight depends on the gravity (eitherMoon or earth)
3rd is true b/c mass is constant (ignoringrelativity)
4th is wrong
5th wrong b/c mass is independent of gravity (unlikeweight)
Recall weight = mass*gravitational acceleration
gravitational acceleration differs on Moon andEarth
