the weight reduces due to change in gravity but mass remains constant
you would be weight "less" as in 0 you wouldn't be able to get on to e.g scales sorry?
We see astronauts floating in space but not on earth.why?
Your weight does not technically change when you go into space, as weight is the force exerted on an object due to gravity. However, in space your gravitational force is reduced (you are in a state of freefall), so you experience the sensation of weightlessness.
The force of gravity keeps us grounded on Earth. Gravity is a fundamental force that pulls objects toward the center of mass of a celestial body, such as the Earth. Essentially, our weight keeps us from floating into space.
To calculate weight in space, you would use the formula: Weight in space = Weight on Earth x (gravitational pull of space / gravitational pull of Earth). Since gravitational pull in space is typically much lower than on Earth (about 0.17 times that of Earth), your weight in space would be significantly less. Keep in mind this calculation assumes a constant gravitational pull throughout the region of space you are in.

Yes. The mass of the object doesn't change, no matter where it is. What does change is the object's weight, because that depends on what other masses are nearby.
In space, weightlessness occurs because there is no gravity acting on objects. As a result, objects and astronauts float freely without feeling the sensation of weight. This is different from mass, which remains constant regardless of location.
It will have the same mass no matter where the object is: free floating out in space or on a planet or on a powerful rocket rapidly accelerating.What will be different is weight, which is only observed while the object is experiencing forces: free floating out in space the object has no weight, but either sitting on a planet or accelerating on a powerful rocket the object does have weight.
The feeling of weightlessness is similar to the feeling you have when floating in a swimming pool. Buoyancy is a pretty good simulation of weightlessness. Although there is NO friction in space so you would be either dead from explosive decompression or (if you were wearing a space-suit) you would bee throwing up in your helmet from rapid spinning.

Sure. Have you seen the video of the astronauts floating around inside their satellites, international space station, space shuttle, Apollo capsule, etc. ?Weight depends on the gravitational field in which the mass is located. No gravity = no weight.

Because weight is based on gravity, and gravity changes throughout space.
The mass of an astronaut does not change when she is visiting the International Space Station. Mass is a property that does not change, but the weight of a person does change in space.
