Does a change in motion occur only if a net force is exerted on an object?
No. Changes in motion can occur in other ways. A change in motion can occur if that object exerts a net force on another object, like another ball on a billiard table. The object could also bump into an immovable object and its motion would change.
How does adding and removing of force affect a moving object and an object at rest?
For an object in motion, a force applied in the direction of the movement of the object would propel it further along that direction. The force should be equal or more than the momentum of the object. If a force in applied against the moving object in a direction opposite to the movement of the object, the velocity of the moving object is hampered. How much this decrease in velocity would occur would depend on the amount of the opposing force. If a sufficiently large force in an opposing direction is applied, it can even stop the object. If the force is not along or opposite the movement of the object, the force can change the direction of the object. If the force that was causing the movement of the object is removed, the object slows down, until it finally stops. For an object at rest, a sufficient amount of force can set the object in motion.
How does a change of velocity occur?
Velocity changes as the result of a force. More specifically, the net force on an object must be different to zero. The net force is the vector sum of all the forces acting on an object.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
What changes occur in position direction and speed of an object when it is acted on by an unbalanced force?
the rate of change of momentum is directly proportional to the net disbalanced force and occurs in the direction in which the force acts - (newton's 2nd law) basically, it accelerates in the direction of the net force acting on the body.
When does acceleraion occur?
Acceleration occurs when there is unbalanced force applied to an object.

How much acceleration will occur if a 10 newton force is applied to a 2012 gram object?
Force=mass x acc. So the accel. will be 10/2.012 which is app. 5metres per sec squared.
What forces occur when something slides?
Sliding friction, (possibly) applied force, gravity, and normal force.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
Why does change in velocity happen?
When velocity changes, that means that the object either moves faster, or moves slower, or moves in a different direction. Any of these changes is called "acceleration". A force is necessary to cause it.
Where does motion occur?
motion occurs when any object is acted on by a force
What changes occur in position direction and speed of an object when it is acted on by an unbalanced force?
the rate of change of momentum is directly proportional to the net disbalanced force and occurs in the direction in which the force acts - (newton's 2nd law) basically, it accelerates in the direction of the net force acting on the body.
What is the driving force behind the changes that occur during puberty?
Your hormones.
Is it possible that no transformation of energy may take place even when a force is applied to a body?
Yes. Forces are constantly applied to objects; for an energy transfer (work) to occur, there must be a force AND movement: work = force times distance.
