According to Newton's first law of motion, what is the reason for the ball falling back to Earth?A) The change in the ball's acceleration is proportional to the force acting on it. 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 __________ measures an object's tendency to resist changing its motion.A) Inertia B) Gravity C) Acceleration D) Mass 9 Which of the following statements is true?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 What causes a falling skydiver to slow down after his parachute opens?A) reference motion B) inertia C) air resistance D) gravity
