Acceleration
A balanced force will NOT cause a change in motion.
motion
Force is any interaction that, when unopposed, will change the motion of an object. Force can cause an object to accelerate, decelerate, stop, or change direction. Essentially, force and motion are directly related, as force is what causes changes in the motion of an object.
I think this question is not phrased very well. Any force can change objects velocity (speed+direction). If fact that is the definition of the force - F=ma any force, by definition itself, can change objects velocity. Maybe you meant what force can change objects direction of motion? In that case - any force that has a different direction (not the same as direction of motion) Any force can change an object's motion.
Balanced forces that net to zero cause no change in an object motion.
Force causes a change in motion (although in some circumstances, you may not be able to observe the change). The types of change are: motion can speed up, it can slow down, or it can change direction.
Any net non-zero force acting on it.
Any part of a force that does not act in the direction of an object's motion does not contribute to the object's speed or change its velocity. This component of force perpendicular to the direction of motion only affects the object's direction or causes it to change its path.
motion
A push, pull, or twist that can change the motion of an object
Inertia is an action that can cause motion.
An external force is a force that causes a change in an object's motion by pushing or pulling it in a certain direction. This force can accelerate, decelerate, or change the direction of the object's movement.
