Maye they do, or maybe they don't. What would you think about a little rectangular
cardboard box, the same size as a brick, that's filled with corn flakes or feathers ?
Do you think it has the same amount of mass that a brick has ?
Not necessarily.
Size of the object will determine the volume of the object and as both are of same size thus they will have the same volume.
Now, Mass = Volume x Density
So both the bodies will have same mass only if they have the same density i. e. they are made up of the same material.
If the density of the material /bodies are different then they will have different mass.
no
no
If the two objects are the same size and made of exactly the same amount of the exact same stuff then no.
not always it depends
Different objects contain different amounts of matter, even if they are the same size. Therefore, two objects of the same size can have different masses.
Yes. Consider that a block of iron has considerably more mass than a wooden block of the same size. The amount of matter contained in a given volume of a substance is called density.
No, they will not, unless they are the same material. Every material has a different density, and mass = density x volume
We cannot say that the mass is same because if objects is same weight varies but not very much, but due to some extra molecules that we cannot see with our eyes the mass varies.
Yes but NO
the size
Yes it does. All objects have gravity but the amount of gravity depends on the mass of the object.
Only for objects of the same material. Mass of an object is proportionate to its size and density. It is not directly proportional to the size of it.
True
No, objects do not always weigh the same. The way this is when more matter is on an object more weight. An object would weigh a different amount in a different gravitational field. For instance an object with a mass of 1 kg weighs 1 kg on earth. Its weight would be different on the moon though the mass would remain the same.
