If the forces acting on an object are equal there is no motion (5N->O<-5N).
If the forces are unequal there is movement (7N-->O<-5N).
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.
Forces that are equal in magnitude, opposite in direction and acting on the same object will not create a change in said objects motion.
Balanced forces that net to zero cause no change in an object motion.
Balanced forces that net to zero cause no change in an object motion.

Because of Newton's First Law of Motion.
Not exactly. 'Motion' or 'change of motion' are not force. But the only way to change an object's motion is to cause the group of forces on it to be unbalanced. If the object's motion is changing, then you can be sure that the group of forces acting on it is unbalanced.
Balanced forces applied on both sides of an object cause it to be still. Unbalanced forces will cause the object to move away from the strongest force.
The action and reaction forces are the forces that cancel each other. They do not change an object motion or cause the object to accelerate.
ANY force can cause a change in motion, as long as the sum of all the forces acting on an object is non-zero. For example, if two people pull on an object in opposite directions, and with forces that have the same magnitude, then the sum of the forces would be zero, and the object won't accelerate.
-- An unbalanced group of forces on an object causes the object to accelerate in the direction of the net force. -- If an object is not moving, then the group of forces on it must be balanced, else it would be accelerated.
No. To change an object's velocity, you need an unbalanced force, i.e., the sum of forces must be non-zero.
