If there are no outside forces acting on a system of particles the total momentum of the system will remain constant; i.e. the center of mass of the system will remain at rest or move at constant velocity.
b. outside forces act on the objects.
Momentum
Forces don't act on other forces - forces act on objects.
The would be balanced forces.

Action-Reaction forces act on all matter.
Is gravity a solid? Physical collisions of solid objects is not the only way that forces can act on solid objects.
Action and reaction forces act on different objects. The forces on one of the objects can still be unbalanced.
That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.
Some Forces do not involve physical contact between the bodies on which they act. -Jauan Williams 3182163642
