Does mass change on different planets?

Answer 1

No, you mass does not change in different planets, but your weight does, because your mass is the amount of matter. If you got to mars, for example only the gravity will change and the amount of particles in your body.

The short answer is no.

Think about it this way 120 pounds of steel on earth weighs 120 pounds. The proper way of explaining it would be the earths gravitational pull exerts a force of 120 pounds on the mass of iron. If you took the same piece of iron to the moon it would weight 20 pounds. The proper way of explaining it would be the moon's gravitation pull exerts a force of twenty pounds on the mass of iron.

It is the same piece of iron in both cases it just weighs different amounts because the amount of gravitation force is different between the moon and and earth.

Answer 2

This is a difficult question to answer exactly since density = mass/volume and there is no way of measuring the mass or volume of a planet exactly, but the estimations are as follows:

• 1) Mercury = 5.427 g/cm³
• 2) Venus = 5.204 g/cm³
• 3) Earth = 5.515 g/cm³
• 4) Mars = 3.934 g/cm³
• 5) Jupiter = 1.326 g/cm³
• 6) Saturn = 0.687 g/cm³
• 7) Uranus = 1.270 g/cm³
• 8) Neptune = 1.638 g/cm³

Answer 3

No. "Mass" is the amount of "stuff" that makes up an object; moving that object from one place to another doesn't change that.

What does change on different planets is the gravitational pull of the planet. The amount of that pull gives your "weight", which will vary from planet to planet.

It's confusing because mass and weight are often expressed in the same units, and, on Earth, your mass equals your weight in those units. But this is merely a convention due to the fact that these concepts were invented on Earth.

Answer 4

No. The mass stays the same but the weight changes.
