The only thing that can do that is force.
You have acceleration any time a velocity changes - like when an object falls down due to gravity, when a car starts or stops, when you start moving or stop moving, etc.

It slows down or stops the object because of the acting force, pulling it back. Thanks, GeekyScienceGirl123 :]
Of course not. A moving object has a tendency to continue moving. It won't just stop, without any good reason - i.e., without a force that stops it.
The frictional force needed to just stop something from moving is called limiting friction, and the object is said to be in limiting equilibrium.
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.
Friction always want to retard the motion of a moving object. So friction slows down and finally stops a moving object.
an object that is moving will keep moving until something stops it

The friction produced that stops an object moving when force is applied is 'static friction'.
A moving object stops when its force is used up. The resistance to change its motion is known as inertia.
There are two main types of friction: kinetic and static. Static friction resist impending motion: the force needed to break before something starts sliding. Static friction stops acting upon the object once it starts moving. Kinetic friction resist motion: the force that is opposing existing motion, i.e. object has already started sliding.

Newton's First Law is called his First Law of Motion. It states that an object in motion tends to stay in motion unless influenced by something else that slows or stops its motion. Likewise, an object at rest - not moving - tends to stay at rest unless influenced by something else that starts it moving.
A moving object stops moving due to friction. Friction may come from the surface on which it is rolling, the air through which it is moving, etc. Objects in a vacuum theoretically, will not stop moving until they run into something else.
