Mass is the quantity of matter as determined from its weight or from Newton's second law of motion.

Is the object in motion? If so then. F = ma: the net force on an object is equal to the mass of the object multiplied by its acceleration.

So if it is moving than it's relativistic mass does change. If it is stationary no.

The mass of an object can change; for example the mass of a rocket changes and nuclear reactions involve changes of mass, b

y E= mc^2.

No, mass can not change in a closed system due to the law of conservation of mass. When density changes it is due to the change in volume NOT MASS!

**Actually, it can!! The law of conversation of mass DOES NOT correctly describe the physics in a nuclear reaction. Mass is converted into energy according to E=MC2. Therefore, mass decreases as energy increases (and is released) in a nuclear rxn. The law of conservation of mass and energy is needed to describe this. It must also be mentioned that this only applies at non-relativistic speeds. As an object speeds up to a fraction of the speed of light, its mass actually increases!!

Typically no. If you make an object smaller or bigger you change it's density, but it's mass remains the same. Only if you take away energy with mass (such as atoms, molecules, etc.), which can effect shape, does the mass of an object change.

Yes and no. A stone in the bed of a fast current river will slowly wear away layer by layer whil a stone on land will most likely stay the same.

No, but its weight does.Because mass is the amount of stuff in one object

yes , because atoms always have the same atomic number , they can have different mass numbers.

No. The mass would remain the same. However, its "weight" as caused by gravity will change according to the gravity of a planet, and also according to its distance from the planet.

Why will a person's mass never change whether they are on earth or on the moon?

Because mass is not the same as weight. Weight is mass times gravity so your weight will change if you are on the earth or moon but your mass will stay the same.


What is its mass on the moon and on the Earth for a box of 16kg?

The mass is 16kg on both the Earth and on the Moon. Mass does not change due to gravitational forces.


Will gravity ever change so it longer holds us?

No gravity cannot change so that it no longer pulls us towards the earth because it is a property of the earth itself. The force of gravity exists between any two masses, even two people, but is much more profound between the earth and us due to the extremely large mass of the earth. Unless the mass of the earth changes, the force of gravity cannot change.
