yes. external forces ALTER an object's motion... but once it starts moving and has no external forces being applied on it, it will go in a straight line with constant velocity (Newton's 1st Law of Motion)
Yes it is possible for an object to be in motion without any forces acting upon it. It may only be possible in theory, though, since it would be difficult to find somewhere in the universe where there are no forces (gravity, in particular) that could act upon something.
The fact is, that once an object is in motion, it will remain in motion until some force arrests (stops) the object. Therefore, the motion must continue if there are no influences from any forces. This answer, of course, assumes that you are ignoring the fact that an object in motion is a force, in and of, itself.
The Theory of Relativity would also support the above statements.
Of course. But it only moves at constant speed in a straight line. A net force
acting on it is required in order for its speed or direction to change.
Yes. If there is no net force, the velocity won't change. That means that if the object was already moving, it will continue moving.
are constant
Yes, the object can have equal forces acting in opposite directions: 5N ->[]<- 5N The object will have forces acting upon it, but will not move.
Yes.
When the forces acting on an object are balanced, they cancel each other out and the result is no change in its motion.Balanced forces have no effect on motion. Unbalanced forces cause acceleration.
Yes. As long as the forces are equal and opposite the object will not change its motion.

Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
An object's motion can't change unless an external force is acting upon it. This is Newton's First Law of Motion.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).

It travels in uniform motion when there are no net forces acting on it.
Balanced forces do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
