It is absolutely true that when the velocity of an object
changes, the momentum of the object also change. Momentum of any object is
defined as the multiple of velocity of an object and the mass of the object. So
we can easily deduce that momentum is directly proportional to velocity of an object
if the mass of the object remains constant. So it can be seen that if the mass
of the object does not change then any change in velocity is bound to have an
effect on the momentum of the object. We can easily write the equation as
momentum= mass x velocity.
