That law is called, precisely, the Law of Conservation of Momentum.
You can't think of momentum as simply "increasing" and "decreasing" - you have to consider momentum as a vector.If in a collision one object's momentum changes by a certain amount, call it "a", the momentum of the other object will change by the opposite amount, "-a" - both "a" and "-a" are vectors that add up to zero. If you consider only the magnitudes of the momentum, by conservation of energy the momenta can't both increase - but they can certainly both decrease, when objects collide head-on.
In a collision, a force acts upon an object for a given amount of time to change the object's velocity. The product of force and time is known as impulse. The product of mass and velocity change is known as momentum change. In a collision the impulse encountered by an object is equal to the momentum change it experiences.Impulse = Momentum Change. What happens to the momentum when two objects collide? Nothing! unless you have friction around. Momentum#1 + Momentum#2 before collision = sum of momentums after collision (that's a vector sum).
In a closed system, the TOTAL initial momentum before an "event" is the same as the TOTAL final momentum (at the end).
Yes, this is called "The Conservation of Momentum". It requires that the two object are "Elastic", that is they do NOT permanently DEFORM. Two automobiles colliding would be an "Inelastic" collision. Energy would be lost in the Deformation of the Sheet Metal of the car bodies, and the amount of Momentum would NOT be the same AFTER the crash.
Newtons law
That law is called, precisely, the Law of Conservation of Momentum.
Newton's Third Law is closely related to Conservation of Momentum. When objects collide, whether the collision is elastic or not, momentum is conserved. (An elastic collision is one in which mechanical energy is conserved. In an elastic collision, after the collision, the objects go away at the same relative speed at which they approached before the collision.)
The total momentum before the collision is the same as the total momentum after the collision. This is known as "conservation of momentum".

The affect of force on the object during collision is described by a quantity called momentum. It is defined as p = mv where = p is momentum, m = mass of the object and v is velocity.
In a closed system, the TOTAL initial momentum before an "event" is the same as the TOTAL final momentum (at the end).
The total momentum of all the objects does not change when two or more objects collide together. An object that is smaller in mass can not have more momentum after the collusion.

The vector sum of momenta before and after the collision is the same. One way to visualize this is that if one of the colliding objects changes its momentum (mass x velocity) in one direction, then the other colliding object must needs change its momentum in the opposite direction - by the same amount, except for the direction.
Momentum of an object is its own property but it can be transferred by that object to any other object during their collision ( elastic or inelastic ) so as to conserve the total momentum of the system as demonstrated by the law of conservation of momentum. One of the examples of the transferring of momentum is the transfer of momentum and incident energy from photons of x rays to the loosely bound electrons in graphite target in Compton effect.
