If a net force acts on a system the system's momentum will change True Or False?
True.

What changes occur in position direction and speed of an object when it is acted on by an unbalanced force?
the rate of change of momentum is directly proportional to the net disbalanced force and occurs in the direction in which the force acts - (newton's 2nd law) basically, it accelerates in the direction of the net force acting on the body.
What is impulse in physics?
Einstiens law of relativity. That does not relate to impulse. Impulse equates to a change of momentum, usually thought of as for a very short time, but doesn't have really to be so short. Now since force = mass times acceleration =m.dv/dt, you can write that as d/dt of mv, so force =rate of change of momentum So force times time (or its integral over time, which is the same thing) must equal simply the change of momentum. In the case where it a very short time, all that happens is that the momentum changes instantaneously.
How can you relate a force with the change of a momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)
How can you related of force with the change of momentum of a body?
Change of the body's momentum = (force on the body) x (length of time the force acts on it)

Will the momentum of a system change when a net force acts on a system?
Yes.
What two characteristics of and object determine the objects 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.
If a net force acts on a system the system's momentum will change True Or False?
True.
What happens to momentum when an impulse acts on a system?
Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
What is the impulse of a baseball that is caught?
Impulse is change of momentum, which is force x time over which the force acts. Original momentum = mv, final momentum =0, so impulse is in this case mv.
