Suppose that the acceleration of an object is zero. Does this meant that there are no forces acting on it?

• No, it means the forces acting on it are balanced and the net force is zero

• No, it means the forces acting on it are balanced and the net force is added

• Yes, it means that the forces acting on it are unbalanced and the net force is equal

• Yes, it means the forces acting on it are unbalanced and the net force is zero
