WHAT CHANGES AS THE MOMENTUM OF AN OBJECT CHANGES?

velocity

The velocity vector can change.

A change in momentum exists whenever a force acts on an object, and the magnitude of the change is dependent on the mass of the object on which the force acts.

Momentum is defined as mass times velocity, so if the velocity changes, the momentum would naturally also change.

The mass doesn't nessessarily change when weight does. The gravity may have changed.Mass and weight need some clarification.The mass of an object is measured in kilograms. That always remains...
