Why is an object's weight dependent upon where in the universe it is located?

Question

anonymous · Answer

A.
	Weight is the magnitude of gravitational force acting on an object. Gravitational force varies in different places in the universe; therefore, weight also varies.
	
 
B.
	Weight is the amount of matter in an object. Because gravity is a force, and force is proportional to weight, both gravity and weight vary in different places in the universe.
	
 
C.
	Gravitational force is the magnitude of weight acting on an object's mass. Weight varies in different places in the universe; therefore, gravitational force and mass also vary.
	
 
D.
	Gravitational force is the magnitude of weight acting on an object. Weight varies in different places in the universe; therefore, gravitational force also varies.

because unlike mass, the weight of something also depends on the force it's being pulled. For example, the weight of a 1kg ball on earth is about 10N. But bring it to the moon and you'll have a different story. Because the force of gravity on the moon is six times weaker than the earth, the 1kg ball (same mass) will have a 1/6 the weight on the moon versus the earth

so the only acceptable answer would be the first one. Mass is constant, but since the gravitational force is different, you have different weight
