Actually it isn't. Matter has several attributes; mass is just one of them.
Yes, mass remains the same when matter contracts. In physics, mass is a measure of the amount of matter in an object, so as long as no mass is added or removed during the contraction process, the total mass remains constant.
Mass is the same no matter where you are. Weight is less, but mass is the same.
Mass is a property of matter but mass is not the only property of matter. Mass and property do not mean the same thing any more than Ford and car mean the same thing.
No. Mass is a characteristic, a property of matter. For many applications, mass and weight can be treated like almost the same.
You cant, the mass will always be the same, NO matter what.
Your mass will stay the same. Mass is always the same no matter what.
The same as on Earth or anywhere for that matter. Your mass stays the same no matter where you are.
No, matter refers to anything that has mass and takes up space, while mass specifically measures the amount of matter in an object. Mass is a quantitative measure of the amount of matter in an object, whereas matter is a general term that encompasses all substances that have mass and volume.
Your mass stays the same no matter where you are. Your weight will change.
the mass will remain same.
I do not think there is anything that does not require matter. Matter has mass, and mass is the same as energy, so if something does not have mass or energy, it does not exist. Even the smallest elementary particle, the muon neutrino, has energy; therefore it has mass; therefore it is matter.
Inertia is related to MASS. MASS is a property of matter. Matter is the same on the Earth or on the Moon. Therefore his inertia would be the same.
