They actually are weightless, due to the fact there is no gravity in space. However a sky-diver would say he/she feels weightless, but they are experiencing free-fall.
Because they are falling (they are in freefall) at the speed that gravity is pulling them.
It's called a space suit
Same as an astronaut. A person trained by a space program to travel into space as a crew member of the space program.
Once in space, an astronaut uses a special breathing apparatus. Corruption had spread throughout the city's political apparatus.
You throw the jetpack. Newton's 2 or 3: law every action has a opposite reaction.
If you mean "Does air occupy space?" then yes it does when we compress air it takes space.. but when its not compressed we may not feel it but it still does take up space..
Yes
It actually means that the astronaut is in free fall, and doesn't FEEL gravity. Gravity does affect the astronaut, so the astronaut will still be accelerated towards Earth. However, the astronaut won't feel the gravity.
yes
when the rockets stop firing, astronauts begin free fall (weightless).
Technically, as an astronaut is weightless in space, so should a space shuttle!
weightless is just a figure of speech. things in space are just lighter than they are on earth. the space shuttle weighs 220,000pds so in space it might weigh 100,000pds.
"Weight" happens when the attraction of gravity on a mass is resisted, we only FEEL the weight when we are resisting gravity. Weightlessness therefore happens when gravity is not resisted - when you are in "free-fall".In a space when you are in orbit round the Earth, you are effectively in "free-fall" and therefore as you are not resisting gravity you are weightless (but not massless).
ahahah nica sorry but i dont answer questions for ugly as people
Yes
The force of gravity on Earth for this astronaut is 50 x 9.8 = 490 Newton. Divide this by 5.6 squared, and you get 15.6 Newton.Note that the astronaut will not feel this force, because he is in free fall; any space capsule he is in will accelerate towards Earth with the same speed as him, and he will feel weightless.
They don't. The moon has gravity but not as much as earth so they feel that they have less weight. In outer space a person would feel weightless because no gravity that they could notice is acting upon them.
-- weightless -- falling -- nausea -- loneliness -- isolation -- insignificant in size
