Question

which one would have more gravitational mass? one kilogram of iron dropped from 200 meters height or one kilogram of paper on the ground?

Answer 1

the piece of paper because gravitational forces between 2 objects depend on the distance between their centre points and the mass, so since they are both the same mass, then the only factor which would determine the force is the distance. The distance between the centre of the earth and the paper is smaller than the iron, so the force would be greaater 

Answer 2

Neither of those objects has more or less mass than the other has. The mass of an object does not depend on its motion or its location. Mass is Mass. The unit of mass is the kilogram. One kilogram is one kilogram. Their masses are equal.
