What new choices does living in a weightless environment give an astronaut?
they have to exercise their muscles wherever they are.
The highest satellite are about 5.6 earth radii from the centre of the earth .this is about a tenth of the way to the moon. what would be the force of gravity be on a50 kg astronaut at this location?
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.
Why does a man feel weightless on the moon?
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.
How do the people who travel in space feel?
-- weightless -- falling -- nausea -- loneliness -- isolation -- insignificant in size
What are Benefits of being a astronaut?
You get to experience living in space, floating around in a weightless environment, and viewing the earth from a third party perspective. Astronauts are viewed as the elite, and are often highly respected.
What anastronaut working in Space near the International space station says she feel weightless. What does she mean Does the astronaut no have weight?
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.
Why do astronaut feel weightless in space?
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.
Why does an astronaut become weightless in space?
Yes
Does an astronaut have mass on the space shuttle if its weightless?
yes
What new choices does living in a weightless environment give an astronaut?
they have to exercise their muscles wherever they are.
Why isn't an astronaut in our solar system in zero gravity?
An astronaut can never be in zero gravity in our solar system, because there is gravity (usually) from the Earth, and always from the Sun. It is important to distinguish weightlessness from zero gravity. Weightlessness occurs in a gravity environment in which the person is freefalling, hopefully in orbit. In a freefall condition, there is no friction to retard your fall, so you feel nothing pressing against you, and thus you feel weightless..When in orbit around the Earth, an astronaut is in freefall, and is therefore weightless, but there is still gravity. When travelling between the Earth to the Moon, the astronaut is still in orbit around the Sun, and is therefore freefalling weightlessly.
What must happen for an astronaut to appear weightless?
He (or she) must float motionless and unattached to any object or cable.
What is a space shuttle like in space?
Technically, as an astronaut is weightless in space, so should a space shuttle!
Are astronauts really weightless in orbit why not?
because both the astronaut and the satellite is attracted towards the center of the earth

Why an astronaut in a space shuttle feels weightless?
"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).
Why an astronaut's digestive system still works even when weightless in space?
ahahah nica sorry but i dont answer questions for ugly as people
