when spacecraft move upward do its mass or weight increase or decrease?

Answer 1

mass is constant, it never increases or decreases
it's weight will decrese as at leaves the Earth because it will no longer be affected by Earth's gravity

Answer 2

Weight decreases as it moves up and fuel is burned, and as the gravitational pull of the earth on the spacecraft weakens. The expenditure of fuel decreases mass to some extent, as the fuel is converted to energy.

Eventually it is weightless, as it enters into orbit. But it will still have its original mass, minus the mass of the spent fuel.

Answer 3

The mass would not change but it's weight would because weight is determined by gravity. As the craft would approach space, it would eventually become weightless. The Earth's gravity would no longer be affecting it. Weight would decrease. Mass is unaffected by gravity so would remain the same.

Answer 4

Its mass stays exactly the same no matter what. In space it doesn't have a weight but note it still has the same mass.

For example. a bag of sugar on earth has a mass of 1kg and weighs 1kg. On Jupiter it still has a mass of 1kg but it weighs a lot more over there.

Answer 5

its mass stays the same and as it goes higher, its weigh decreases.
