An object at rest cannot start moving with no forces.
If the object is not moving, then the only thing you can be sure of is that since it's not accelerating, all of the forces acting on it add up to zero. Just the fact that it's not moving is not enough information to tell you that there are no forces on it.
Forces that likely act upon a moving object include:frictiongravity
Then the result will be the same as if NO forces act on the object (since the sum of the forces is zero). The object will continue moving in a straight line, at constant speed.
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.

The object will maintain its speed and direction or the object will not change its speed or direction.
When all forces are balanced, the object can either be moving at a constant velocity or be at rest. But because you asked for balanced forces on a moving object, it is moving at a constant velocity.

Balanced forces will not change the velocity - speed and direction - of a moving object. the object will continue to move in the same way.

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.
A group of balanced forces adds vectorially to zero, so has no effect on any object, whether it's moving or not moving.

An object at rest has zero acceleration. If the set of forces acting on a moving object is balanced, then the moving object also has zero acceleration.
That's true. Plus ... even if the forces on an object are BALANCED, it can keep moving forever.
