If a ball is accelerating downward through the air with no horizontal motion, it implies that the ball is experiencing a net force in the downward direction.
In this scenario, the gravitational force acting on the ball (downward) is greater than the drag force (upward) that air exerts on it. This results in a net downward force, causing the ball to accelerate downwards.
Therefore, the correct statement is: The gravitational force is greater than the drag.
