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 Change in momentum times time?
Impulse = [(change in momentum)/time]*time[(change in momentum)/time] = ForceAnd when force acts for a period of time, that impulse changes the momentum of the object.You can also rewrite the impulse equation as: I = F*tHowever, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m. These units are not in common usage.
Will the momentum of a system change when a net force acts on a system?
Yes.
Will the momentum remain constant if some external force acts on the system?
no
How can you relate a 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)
What is the momentum law the states that the total momentum of an object is constant if no outside force acts on it?
Law of inertia? Newtons first law.
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.
Is impulse a vector quantity?
Two reasons. Recall impulse is the change in momentum. First the momentum is a vector. So imagine a triangle. One side is the initial momentum (with one direction), the second side is the final momentum (with a potentially different direction) and the third side is the impulse (or change in momentum). The other way to look at this is in terms of what causes the change in momentum. This is how impulse is generally described. The impulse can be defined as the average force acting on the particle multiplied by the time interval over which the force acts. This is sometimes represented as the integral of the force. As force is a vector so is the impulse caused by this force.

What are two ways to increase momentum?
By increase the objects mass and its velocity, Since Impusle (F x t) is the change in momentum and momentum is (Mass x Velocity) Impulse depends on the magnitude of the applied external force and the time that the force acts on the system. By increasing either of those, impulse on a system will be increased, and the system's momentum will change accordingly.
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.
When is the angular momentum of a system not conserved?
The angular momentum of a system is not conserved when a net external torque acts upon the system.
Will the momentum of a system change when a net force acts on a system?
Yes.
If you increase force keeping the area the same what happens to pressure?
if force increaces and area stays the same then pressure
If a net force acts on a system the system's momentum will change True Or False?
True.
Will the momentum remain constant if some external force acts on the system?
no
