An object moving along a straight line is decelerating. Which one of the following statements concerning the object's acceleration is necessarily true? 1. The value of the acceleration is positive. 2. The direction of the acceleration is in the same direction as the displacement. 3. An object that is decelerating has a negative acceleration. 4. The direction of the acceleration is in the direction opposite to that of the velocity. 5. The acceleration changes as the object moves along the line.
