B) It is accelerating in the same direction as Earth's gravitational force on it. C) The ball exerts a force on the air surrounding it. D) A force has acted on it. 8 A) Inertia B) Gravity C) Acceleration D) Mass 9 A) An object does not accelerate if it turns and maintains constant speed. B) If a moving object slows, it is accelerating. C) Velocity of a moving object is the distance traveled divided by the time needed to travel the distance. D) When speed increases gradually, average speed and instantaneous speed are the same. 10 A) reference motion B) inertia C) air resistance D) gravity
