That's it. A force is a push or pull on an object.
Either a balanced group of forces is acting on it, or else zero force is.
That depends. If no forces act on the object, it will. If forces do act on the objects, such forces may change the object's velocity.
Forces that likely act upon a moving object include:frictiongravity
If the object doesn't move, the forces HAVE TO be balanced. There is no other way.
If forces on an object are balanced, the object will not accelerate - i.e., its velocity won't change.

Because NOT all forces are equal and opposite. By Newton's Third Law, if object A attracts object B, then object B also attracts object A - with an equal but opposite force. But those forces act on DIFFERENT objects! The forces on object A, and on object B, may be unbalanced!Because NOT all forces are equal and opposite.

If forces on an object are unbalanced, the object will accelerate or decelerate. If forces on an object are balanced, the object will stay still or keep moving with the same velocity.
