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.
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
The idea is that there is a quantity, "amount of movement", formally the product of mass x velocity, that is conserved. That means that the total momentum doesn't change, even if two objects collide, for example - any momentum lost by one object is gained by the other object.

What will change is the momentum.

It is called the momentum-impulse theorem and states that an impulse will change the momentum of an object. For example, if you drop an object when it hits the ground an impulse occurs. The momentum of the object also changes. Jnet = deltap, where deltap is the change in momentum.
The mass of the object and its speed.

Increasing the speed of an object will increase its momentum as well (momentum=mass*velocity).
The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
Momentum is a measure of how much force it takes to stop something in a certain amount of time. If it takes 10 N to stop object A in 30 sec and it takes 15 N to stop object B in 30 sec, then B has more momentum; 50% more momentum.
A change in momentum exists whenever a force acts on an object, and the magnitude of the change is dependent on the mass of the object on which the force acts.
In order to impart the greatest momentum to an object, you should both exert the largest force possible upon the object in question and extend that force for as long as possible. This is so because the greater the force acting on an object results in a greater change in velocity, which in turn yields a greater momentum. In addition to exerting the largest force possible on an object, you should also extend that force over the longest period of time as possible, as the sustained force also produces more momentum. As p= m•v, the best method in obtaining the greatest amount for 'p' would be to manipulate either the 'm' or 'v' variables. Force= acceleration= change in velocity= MOMENTUM. Greater amount of time= MOMENTUM
