There is no force that maintains motion by itself. Motion is maintained by Newton's Law, that objects in motion tend to stay in motion. Forces can act to stop the motion, such as the force from friction, in which case some other force, such as the force provided by a car's engine, is what keeps the car from slowing down and stopping. But, in the absence of forces acting against motion, such as friction, an object will remain in motion with no forces acting on it.
No force is required to maintain a motion. For more information, do some reading on Newton's First Law. While you are at it, also do some reading on Newton's Second Law, which is closely related to the First Law.
A force that maintains motion is called inertia. This is the same as to what is normally referred to as momentum.
Sticking. An extra force is required to start the motion, above the force required to maintain motion.
Newtons first Law
No, a force is not a motion. A force may produce motion of a mass.
Newton's 1st Law of Motion states that an object will maintain its speed when there is no net force acting on it. The question refers to free space and constant velocity -- the net force has to be zero. =========================
It could be called superfluous. No force is necessary to maintain motion.

Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
The object will remain at rest if it was at rest or will maintain its motion with uniform velocity if it was moving.

Inertia. A body, once set in motion wants to maintain that motion, until acted upon by another force.

No, motion is not a force. Motion is a change of coordinates. However, motion usually is a result of applying a force.
Force has size, which is how much force put into somethig, e.g., 10 Newtons of force. It has motion because force is basically motion, because force can be unbalanced or balanced, and unbalanced causes motion, and is basically motion.
