Question

how do a force changes the momentum of an object

Answer 1

A force acting for a given amount of time will change an object's momentum. Put another way, an unbalanced force always accelerates an object - either speeding it up or slowing it down. If the force acts opposite the object's motion, it slows the object down. If a force acts in the same direction as the object's motion, then the force speeds the object up. Either way, a force will change the velocity of an object. And if the velocity of the object is changed, then the momentum of the object is changed.

Answer 2

Knowing the amount of force and the time of force when it applied to an object this will result in change of Momentum. They are related by the fact that force is the rate at which Momentum changes with respect to the Time.
