Which of the following statements are true of an object that experiences balanced forces (or unbalanced forces)? List all that apply. If a person is moving to the right, then the forces acting upon it are NOT balanced. A balance of forces is demonstrated by an object which is slowing to a stop. It would take an unbalanced force to keep an object in motion. If an object is moving with a constant speed in a circle, then the forces acting upon the object are balanced. If an object is accelerating at a constant rate of acceleration, then the forces acting upon the object are balanced. It is NOT possible for just three forces to be acting upon an object and they still balance each other. A free-falling object experiences a balance of forces. Balanced forces cause stationary objects to remain at rest and moving objects to come to rest. Unbalanced forces cause objects to move.
