It is the force of inertia.
Yes. If no force acts on an object, it will continue moving indefinitely.

This can be explained with Newton's First Law of motion, Inertia. An object in motion tends to stay in motion until a force acts on it. When you are walking, your entire body is moving forward. But if your toe hits an object, only it will stop. So the rest of your body will continue moving forward until you stop yourself. (hopefully before you hit the ground)
Inertia
Balanced forces will not change the velocity - speed and direction - of a moving object. the object will continue to move in the same way.
Friction opposes the motion of one object moving past another. Objects at rest remain at rest and objects traveling at a steady rate in a straight line continue that way until a force acts on them.
inertia
Newton's First Law states that an object that is moving has the tendency to continue moving at the same speed; if it is at rest, the tendency is for the object to remain at rest. This law is also known as the law of inertia.
the force or other moving object
unbalanced
In this case, it is as if no force acted on the object. The object won't acceleration; if it is resting, it will continue resting, and if it is moving, it will continue moving at the same velocity.
... continue to do that, until a force is exerted on it.
