They go underwater in a giant pool of water, it is the closest to 0 gravity on earth. Occasionally, they go into a plane called 'Vomit Comet'. The plane goes high up in the atmosphere and descends rapidly over a period of 30 seconds. The plane's descending speed hits the astronauts terminal velocity, hence the astronauts can simulate what it feels like to be weightless.
trained space astronauts
A very small amount of gravity. (As opposed to the macrogravity on earth). Often called zero-g, but there is not 0 gravity anywhere.
Yes. Gravity is what keeps them in orbit. If it were not for gravity, those astronauts would continue out into space in a straight line.
No, the word 'astronauts' is a noun, the plural form of the singular noun 'astronaut'; a word for someone who is trained to travel in a spacecraft; a word for a person.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
yes
Lack of gravity.
they do-there is no gravity
Because of the gravity of the
Astronauts in space experience microgravity, where they are in a state of continuous free fall around the Earth. This creates the sensation of weightlessness. They do not completely overcome gravity, but rather experience an environment where the effects of gravity are significantly reduced due to the spacecraft's orbital motion.
Yes, astronauts can fly out here and there as they live in zero gravity in space.
Gravity is a non-contact force that acts between two masses.
