Yes.
For the velocity of an obejct to change (e.g. to make a moving object slow down and stop) there must be a resultant force acting on it. This only occurs if the forces acting on it are unbalanced.
Yes.
For example :
When we cycle fast and while going if we cross a speed breaker or an area of the road which is not smooth , there will be more friction thereby reducing the speed of the object or otherwise stopping it.

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
What do balanced forces do to an object?
Balanced forces keep object in its state of motion (moving or at stop). An objects state of motion can be altered when it is subjected to an unbalanced force. This reflects Newtons first law of motion.
What always happens to the motion of an object when unbalanced forces act on it?
There's no such thing as "an unbalanced force".When the group of forces acting on an object is unbalanced, then the objectaccelerates, in the direction of the vector sum of the forces.
Are the forces balanced or unbalanced when you push a box of books until it is moving at 0.5 miles per second?
During the time, you're pushing it, the forces are unbalanced. Once you stop, they are balanced. Unbalanced forces result in a change in motion. Balanced forces produce no change.It's kind of funny that you're pushing your box 1800 miles per hour, though! :)
Examples of 1st law of motion?
Uniform motion in a straight line: An object in the situation has a constant velocity. An object at rest has a constant velocity of zero. Basically what this means is that if these objects are left alone, they will continue to move at the same speed and direction as they are right now (or lack of). External force: This is any force from outside the object. For instance, a moving car will stop if it hits another moving car, but not if you step on the floorboard because stepping on the floorboard is an internal force. Unbalanced forces: These are forces that are not equal and cause motion. If the forces were balanced, there would be no motion. At rest: The object is not moving at all (or seemingly).
What happens if a balanced forces are applies to a moving object?
When balanced forces are applied to a moving object, the object likely slow and eventually stop. How quickly that occurs depends on the amount of force.
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

Force causing an object to start moving?
what starts to move an object is force because it's pushing on the object and what stop's the obect from moveing is force too because if the force is going the oppisit way its going to stop the object.
Which forces are unbalanced?
coz if they werent, whatever they were acting on, would either stay sill, or move at a constant speed
How can you tell when balanced forces are acting on an object?
It will stop moving.
How can an object have balanced forces and still move?
If an object is at rest it takes an unbalanced force to get it moving. Also if an object is moving it takes an unbalanced force to stop it. So if an object is in motion, because of some unbalanced force and then, while moving, another force comes in to make the forces balanced this will not be enough to stop it, just keep it from accelerating. This happens when objects are dropped from a great height. At first the force of gravity causes it to pick up velocity (accelerate) as it falls. But as it picks up speed the force of air resistance gets larger and larger. Pretty soon the downward force of gravity is just balanced by the upward force of air resistance. The object continues to fall , but now at constant velocity.

What forces slow down and stop an object moving trough air?
friction
Why don't things stop when you push it like a ball on the ground?
Things will eventually stop if there is a force to stop it... and no force that keeps it moving. If there are no forces on an object, or the forces are balanced (the friction forces on a car are compensated by forces that pull it forward), it will continue moving.
What happens to the motion of an object when an unbalanced force acts on it?
The object accelerates in the direction that the greater force is pushing or pulling it.any object is acted upon by an unbalanced force will make the object move with the unbalanced force as there is not the right amount of the other force to stop it.if they were balanced forces the object would find equilibrium and would end up basically being held in one place, or travel on one vector without changing course.As for an object under the effect of unbalanced forces? It would NOT behave like the one described above. that is all that could be said.The object accelerates in the direction of the 'net' force ... the vector sum of allof the individual forces. The rate of acceleration is proportional to the magnitudeof the net force.It (the motion) is changed.(Your last it being the object ... I hope).when an unbalanced force act on a moving object, the velocity of the object will change.When an unbalanced force acts on an object, the object will accelerate. This is a fundamental law of physics that goes back to Newton. Further, the object will move in the direction of the unbalanced force.We know that force is equal to mass times acceleration (F = m x a). If force is applied, the object is accelerated in the direction that the force moves it. If force increases, the object will accelerate more because acceleration must also increase.There's no such thing as "an unbalanced force".When the group of forces acting on an object is unbalanced, then the objectaccelerates, in the direction of the vector sum of the forces.
