It wouldn't accelerate. It would move at a constant velocity due to its tendency to keep moving (inertia) and friction being canceled out by the horizontal force.
If there was no force then there would be no balance to keep things in place
When a child is being pushed on a swing, it is an example of an unbalanced force. The force provided by the push helps to overcome the force of gravity to keep the child swinging.

That's "centrifugal force". It's not a "real" force like gravity, but is a convenient way of describing the effect of the inertia of the planets. (The planets would move in straight lines if they were not in a gravity field.)
They thought this would keep them out of debt.
The force needed to keep a 20N stone from falling would need to be 20N or greater in the opposite direction to counteract the force of gravity pulling the stone downwards. This force would need to be applied vertically upwards to effectively balance the gravitational force acting on the stone.

The upward normal force from the ground pushes against gravity to keep you from sinking into solid ground when you stand. The normal force is caused by the atoms in the ground that resist being compressed by your weight, resulting in a balanced force keeping you upright.
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

Not being in Europe...
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
