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.

Yes
If you apply force to an object, you accelerate it. If you apply the force in the direction that the object is moving, you speed it up. If you apply it in the opposite direction, you slow it down. If you apply the force in another direction than the object is moving in you will change the direction of the objects motion. The amount of acceleration is given by a = F/m where a is acceleration, F is force and m is the mass of the object.
Yes, a force can cause an object to move, or to change its speed or direction. A net force that is non-zero is one that acts in this manner, and it represents the "sum" of the forces acting on an object. If the net force on an object is not zero, it is some number, and this represents a force that will act on an object to accelerate it.
A net force from something outside of the system.
. The amount of Force needed to make an object change its motion depends on the Mass of the object and the Force required
To make an object move, a force is required. To change the direction of an object's motion, a different force must be applied in the desired direction. To stop the motion of an object, a force opposite to its direction of motion, known as a braking force, can be applied.

To change the speed of an object, you need to apply a force to it. The magnitude of the force and the direction in which it is applied will determine how the speed changes. If the force is in the same direction as the motion, the object will accelerate; if the force opposes the motion, the object will decelerate.
With changing the "state of motion", I assume you want to change the velocity. What you need here is a force, applied on the object. The amount of acceleration is given by Newton's Second Law.
A force.
It takes no force to 'move' an object. There are trillions of objects that are moving right now with no forces acting on them. It only takes force to 'accelerate' an object ... to change its motion, by changing its speed or the direction of its motion. force=mass*acceleration As mass increases, so does the force needed to change the object's motion.
The concept related to the amount of force needed to change an object's motion is inertia. Inertia is the tendency of an object to resist changes in its velocity. Objects with more mass have greater inertia and require more force to change their motion.
Inertia is the tendency of an object to resist changes in its motion, while force is a push or pull that can cause an object to accelerate or decelerate. Inertia determines how much force is needed to change an object's motion - the greater the inertia, the greater the force required to change its motion.
