If gravity changes, which quantity would change for an object with the same amount of matter?

Explanation:
Gravity affects weight, not the amount of matter. Weight is the force with which gravity pulls on an object's mass, and it changes when gravity changes because weight = mass × gravitational field strength. The mass stays the same, since it’s just the amount of matter, and volume isn’t typically altered by gravity for a solid object, so density (mass per volume) stays the same as long as the mass and volume don’t change. So, with the same amount of matter, the quantity that would change when gravity changes is weight.
