When any force that is not exactly canceled by another force acts on an oblect,
the oblect's speed or direction of motion or both must change. Any such change
is known as an 'acceleration'.
yes every unbalanced force can change or "try to change (can be or cannot be)" the state of rest or motion

an unbalanced force.
There's no such thing as "an unbalanced force".If the entire group of two or more forces on an objectis unbalanced, then the object's motion changes.
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.

Yes.
it takes an unbalanced force to change an object's state of 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.
