Yes.
The reason is because the mass is like the volume and the weight is like how heavy an object is.
Mass is the amount of matter an object has. Weight is actually a measure of the force of gravity on an object. An object normally has a constant mass, but weight varies with gravity. An object in space will have no weight, but still have the same mass.
No, not unless they are made of the same substance. Different substances have different densities, which means that the same volumes will have different masses.
The mass of the object is the same as it was when you measured it on Earth, but its weight is different in other places.
Gravity.
no
The shape of an object bears no relation to the mass of an object.
No, there is an air resistance which resists its motion. it depends on the shape and size of the object.
in a vacuum, yes, all objects would fall at the same rate, but otherwise no due to air friction
Yes, but the weight of that mass will be different.
Mass b > mass a
The answer is weight.
Because the shape and size of the object dont change, only the gravity affecting it
Because the shape and size of the object dont change, only the gravity affecting it
Yes. (Unless you were to add to or remove form the object to change the shape. For example, a book will not have the same mass if you rip some pages out.)
No. Not unless its mass is different. But then it wouldn't be the same object.
The reason is because the mass is like the volume and the weight is like how heavy an object is.
