What is a force that causes an object to change its motion?
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.
What must be applied to a objects in order change the objects motion or direction?
A Force.
An unbalanced force will not change an objects motion?
If the forces on an object are unbalanced then the objects motion will change. It will start accelerating in the direction of the resultant force. Only objects that have balanced forces will remain in the same motion (stationary or moving at a constant speed).
A force acting on an object does no work if?
the force is not in the direction of the objects motion.
How does the force required to move an object change depending on the objects mass?
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.

Do objects in motion always change position and may change direction?
Objects in motion continuously change position.To change direction, a force needs to act upon them.

What changes a objects speed and motion and direction?
A force.

When does an objects motion change?
The motion of an object will change when it is acted on by some force. This force will speed it up, slow it down, change its direction of motion or perhaps cause it to spin. All thses changes of motion are response to the force acting on the object. This is Newton's first law: An object in motion will continue in motion (and in the same direction) unless acted on by some force. Some might call this the law of inertia.
Does a force always change an objects motion?
it usually does, but if the force is balanced, it will not change the object's motion
How does the direction of the force of kinetic friction is related to the direction of of an objects motion?
Friction always acts opposite to the direction of motion.
How the direction of the force of kinetic friction is related to the direction of an of an objects motion?
Friction always acts opposite to the direction of motion.
Can a unbalanced force change an objects motion?
An unbalanced force can: change the speed an object moves at change the direction an object is moving cause an object to start/stop moving
