    Explanation:

    The momentum of an object is given in terms of its mass and its velocity. The law of conservation of momentum says that the net momentum of a system remains conserved for an isolated system.

    Momentum is given by :

    p = m × v

    If p is conserved, velocity is inversely proportional to the mass of an object. When mass changes, velocity also changes but inversely.
