Typically, an astronaut and their vehicle are in free fall around the Earth (orbit). This feels like going down a big hill on a roller coaster, but it doesn't stop until reentry.
If you sat on a weighing scale while riding a roller coaster, you would see your weight change with changes in momentum as the roller coaster climbed, fell, banked etc.... Say you normally weigh 150lbs, when you're climbing up the big hill, the scale would show you weighing more than 150 (your weight plus the acceleration as you gain altitude). When you crest the hill and plummet downward, the scale will read much less than 150lb, as your seat, the scale & YOU fall back towards the ground.
Likewise, an astronaut sitting on scale would weigh more than normal during lift off and climbing to orbit. Typically, astronauts will weigh 2-4 times their normal weight during this time. Once the spacecraft is in orbit, it is in continuous free fall around the Earth. The scale would read "0" (zero).
What else can I help you with?
Where does an astronaut start to feel weightless?
when the rockets stop firing, astronauts begin free fall (weightless).
What new choices does living in a weightless environment give an astronaut?
Living in a weightless environment allows astronauts to move more freely, conduct experiments that require a lack of gravity, and experience changes in their perception of motion. This environment also offers unique opportunities to study the effects of microgravity on the human body.
Why does an astronaut still have the same mass on the moon?
Your mass is the amount of matter that contains, it is your weight that will differ due to gravity. The astronaut still has the same amount of matter whether he be on earth, in space, or on the moon, though due to the different strenghts of gravity he will weight the most on earth, 1/6th of this on the moon, and be weightless in outer space.
Can an astronaut in space travel by pushing herself forward?
Yes, an astronaut in space can travel by pushing herself forward using the principle of conservation of momentum. By pushing off a surface or object, the astronaut will move in the opposite direction with an equal force due to Newton's third law of motion. This method allows astronauts to navigate and move around in the weightless environment of space.
The statement that astronauts on the Moon are weightless is?
The statement that astronauts on the Moon are weightless is true.
Why does an astronaut become weightless in space?
Yes
Does an astronaut have mass on the space shuttle if its weightless?
yes
Where does an astronaut start to feel weightless?
when the rockets stop firing, astronauts begin free fall (weightless).
Why does an astronaut have to exert a force on a weightless object in order to move it?
An astronaut has to exert a force on a weightless object in order to move it because in space, there is no gravity to naturally pull or push objects. Therefore, the astronaut must apply force to overcome inertia and move the object.
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.
What is a space shuttle like in space?
Technically, as an astronaut is weightless in space, so should a space shuttle!
What must happen for an astronaut to appear weightless?
He (or she) must float motionless and unattached to any object or cable.
Are astronauts really weightless in orbit why not?
because both the astronaut and the satellite is attracted towards the center of the earth
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.
What is a sentence for weightlessness?
The weightless astronaut landed on Mars, which has no gravity.
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
Could an astronaut be crushed to death between two huge girders moving toward each other in space even if they were weightless?
Yes
