Assuming no air resistance, an object dropped on Earth experiences a constant acceleration of about -9.8m/s^2. Which of the following statements are true?
A. This means that the object’s velocity as it falls is 9.8 m/s.
B. This means that the object covers 9.8 m each second that it falls.
C. This means that the object covers 9.8 meters during the first second of its fall.
D. This means that the velocity of the object increases 9.8 m/s each second as it falls towards the Earth.
