A weight is measured on the Earth or other planet or moon. A mass is identical to weight on Earth, and so is used everywhere else so that we have some way to compare objects that might come from very different places in the Universe. Also, using mass, a physicist can use the same formulas no matter where the objects they are studying are located. Imagine if they had to have a different formula for each separate space object! There would have to be billions and billions of different formulas!

You could say that weight depends on the force of gravity for the massive (get it? mass-ive?) planets, moons, and so on that it is near. Mass is simply a measure of how much material is packed into a given object.

When does the weight of a body change?

The weight of a body changes when there is a change in the gravitational pull acting on it. This can happen if the body moves to a different location where the gravitational force is different, like going from Earth to the Moon. The weight can also change if the mass of the body changes, as weight is a result of the force of gravity acting on an object's mass.


What remains the same when gravity changes Weight or mass?

Mass remains the same when gravity changes, while weight changes. Mass is a measure of the amount of matter in an object and remains constant regardless of the gravitational force acting on it. Weight, on the other hand, is the force of gravity acting on an object's mass and will change with variations in gravity.


What stays the same when weight changes with gravity?

When weight changes due to gravity, mass remains the same. Mass is the amount of matter in an object, while weight is the force exerted on an object due to gravity. So, when the gravitational force changes, the weight of an object changes, but its mass remains constant.


Is mass and weight changes with change of place?

Weight changes depending on the gravitational pull exerted on an object, i.e. if it is on the Earth or if it is on the moon. Mass, however, remains constant.


Is weight measured of the gravitational force on an object?

Weight is gravitational force on an objects Mass. Mass don't change when gravity changes but the weight does.


Is the weight of an object gravitational force of an object?

Weight is gravitational force on an objects Mass. Mass don't change when gravity changes but the weight does.


What is the conversion of mass to weight?

To get the weight, multiply the mass by the acceleration of gravity wherever the mass happens to be at the moment. Dependoing on local acceleration of gravity, the weight changes from place to place.


What is the relationship between wight and mass?

Weight changes based on were you are while mass doesn't. For example, if you are on the moon your weight is much less but your mass is the same.
