Question

An object's will remain constant throughout the universe, but its can change from planet to
planet.
If you increase the mass of a planet, what happens to its gravity?
If the gravity on a planet decreases, what happens to the weight of an object on that planet?

Answer 1

What will happen to the gravitational force between two bodies if the masses of both the bodies are doubled?

If the mass of both of the objects is doubled, then the force of gravity between them is quadrupled; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

Answer 2

Answer:

An object’s  

✔ mass

will remain constant throughout the universe, but its  

✔ weight

can change from planet to planet.

If you increase the mass of a planet, what happens to its gravity?  

✔ strength of gravity increases

If the gravity on a planet decreases, what happens to the weight of an object on that planet?  

✔ weight decreases
