Mass is NEVER the same as weight. Not on Earth, not elsewhere. Those are two very different concepts. Mass is measured in kilograms, weight in Newton, which is the same as kilograms x meters / seconds2.

On Earth, weight is simply more or less PROPORTIONAL to weight, meaning that every kilogram will weigh approximately 9.8 Newton.

For more details, see the Wikipedia article on "mass versus weight".

How the weight and the mass will change if a planet has gravity half as strong as Earth?

Mass remains the same; weight will be one half that of the same mass on earth.


Dan has a mass of 55 kg on Earth. What is his mass on a planet that has twice Earth's gravity?

Dan's mass is the same as it is on Earth. His weight, however, is doubled.


What is Saturn's amount of mass?

Your mass is the same wherever you are, on Earth, on Saturn, on the Sun. Your weight changes if you are on a different planet.

Dan's mass is the same as it is on Earth. His weight, however, is doubled.


What happens to the mass and weight of an object if it is transported to another planet?

The mass of the object remains the same since it is a measure of the amount of matter in an object, but the weight changes because weight is dependent on gravity, which varies from planet to planet. If the gravitational force on the new planet is different than on Earth, the weight of the object will be different.


How would your weight change on the surface of an Earth-sized planet whose mass were greater than Earth's?

If the planet were the same size as Earth but its mass were some percent greater than Earth's mass, then your weight there would be that same percent greater than it is on Earth. A bathroom scale on that planet might not read exactly the number that I have described ... your apparent weight, as displayed by a bathroom scale, would also be influenced somewhat by the planet's rate of rotation, which might be something different from 15° per Earth-hour of time.


If a mass is 80 kg on earth is it more less or the same on the other planets?

A mass of 80 kg will be the same, no matter where you put it.However the weight, as measured by scales, will differ.Fg varies from planet to planet Fg of Earth is 9.8


Would weight increase or decrase on the surface of an earth sized planet with greater mass than earth?

If you're the same distance from the center of the planet but its mass is greater than earth's mass, then the mutual gravitational force between you and that planet is greater than on earth, and you'll "weigh" more than you do here.


What iner planet has same mass as earth?

Venus has almost the same mass as Earth.


If your mass is 45 kg which is about 100 pounds on Earth what will be your mass on Jupiter?

45 kg. The same. Your mass doesn't change on which planet you're on, but your weight does.


Why your weigt increases on other planet?

Your mass stays the same but your weight is different because it is the force that the planet's mass attracts your mass with. So if you are on a small planet your weight is less. A body with 100 pounds mass has a weight of 100 pounds on the Earth but only 17 pounds on the Moon, and zero pounds in space.


Is the Earth the same weight even with 6.5 billion people?

Yes. All the mass that makes up all the people on Earth came from Earth and is a part of it.
