An object's (mass or weight) will remain constant throughout the universe, but its (mass or weight) can change from planet to pl
anet. If you increase the mass of a planet, what happens to its gravity? (Strength of gravity increases, strength of gravity decreases, strength og gravity stops completely) If the gravity on a planet decreases, what happens to the weight of an object on that planet? (Weight increases, weight decreases, weight stays the same)
