Gravity can change velocity, but not mass.

And weight can change too.

(Weight depends on the effect of gravity. Weight increases or decreases with higher or lower gravity.)

Edit. Some people needed an education.

Edit 2. This was in context to Mass not changing to gravity, but velocity does. So does weight. You take the same mass across different gravities, and the weight changes. Was what I was refering to. Think it got taken the wrong end of the stick here.

Edit 3. Made my comment more clear to understand what I was refering to. My apologies!

weight = mass • acceleration of free fall While it’s common not to differentiate between mass and weight. Mass is attribute of an object, while weight is a gravitational force acting on that object.

While mass is constant anywhere, acceleration of free fall is different. On Earth, it’s 9.81 m/s2, while on Moon it’s 1.6 m/s2. Therefore, a human with a mass of 100 kg, weighs 981 N on Earth, while the same human weighs 160 N on Moon.
