Weightless
when the rockets stop firing, astronauts begin free fall (weightless).
In a free fall environment, you do not have gravity to separate things for you, so a centrifuge is a workable alternative.
Weight is an expression of the gravitational force acting on an object. When the space shuttle is in orbit around the Earth, it is held there by the Earth's gravity. Since gravity is still acting on the shuttle and the astronauts inside, they still have weight. They are described as "weightless" because an object in orbit is in a constant state of free fall.
They are essentially in a state of permanent free-fall. Their ship is falling to earth at the same rate as the curve of the earth is falling away form them; ergo continually falling. It has nothing to do anything 'anti-gravity'.
Astronauts should and do exercise in freefall
Free fall
they are not actually flying they r in continous free fall
Weightless
As there is no gravity in space, everything will float........... Because They're in free fall ........
When you jump/fall from an inthinkable height without parachute or any other safety devices. When a bird retracts its wings and fall striaght down it is consiered a free fall.

It's called micro gravity but basically yes. They are just falling around the planet.

Yes, but they do not "feel" gravity, because they are falling - "free fall" in orbit around the Earth.
Not quite. It explains why they have no weight. But their mass doesn't change.It's the same on earth, on the moon, and everywhere in between.
astronauts use space pen because as there is 0gravity in space ink will not fall on the paper
