What happens to an object when the forces acting on it are balanced?

• It slows down and eventually stops

• It moves in the opposite direction of the force

• It accelerates in the direction of the force

• It does not change in motion. If it is at rest, it will stay at rest. If it is in motion, it will stay in motion at the same rate.
