Momentum is mass in motion, and any moving object can have momentum. An object's change in momentum is equal to its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it's the increase or decrease of an object's momentum.

The change in momentum of a particle during a time interva equals the impulse of the net force that acts on the particle during that interval.

J=P2-P1.

Impulse:

In classical mechanics, impulse (symbolized by J or Imp ) is the product of a force, F, and the time, t, for which it acts. The impulse of a force acting for a given time interval is equal to the change in linear momentum produced over that interval.

Momentum:

In classical mechanics, linear momentum or translational momentum (pl. momenta; SI unit kg m/s, or equivalently, newton second) is the product of the mass and velocity of an object.

The impulse–momentum theorem states that the change in momentum of an object equals the impulse applied to it. The units of impulse and momentum are equivalent [N s = kg m/s]. The impulse–momentum theorem is logically equivalent to Newton's second law of motion (the force law).
