A change in velocity - for example, a motion when there was no previous motion - occurs if an unbalanced force is applied to an object.
yes every unbalanced force can change or "try to change (can be or cannot be)" the state of rest or motion
unbalanced foeces
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 do not change its motion (no acceleration). Unbalanced forces changes the motion of the object (acceleration).
If the group of forces acting on an object is unbalanced, the object's motion always changes. The change is called "acceleration".
forces push and pull on an object making the object move in the direction of the force. the stronger force would overcome the lesser force, causing the object's motion to go in the direction of the stronger force (newton's 2nd law).alsoif forces are balanced there s no acceleration hence there is no motion.....thus if forces are unbalanced the motion is in the same direction as the resultant force (the greater force acting on an object)When the forces acting on an object are unbalanced, The one with more mass will pull on the other one, causing a change in motion.
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.
