The launch conditions do not define free fall. The object may be launched with an initial velocity directed upward or downward. The initial velocity may also be zero.
If an object is in free fall, which of the following statements must be true?
Mark all the correct statements among those provided below.
A. The initial velocity is zero.
B. The object is moving vertically.
C. The object is moving downward.
D. The only force acting on the object is the force of gravity.
E. The only forces acting on the object are the forces of gravity and air resistance.
F. The acceleration of the object is constant.
G. The acceleration of the object is decreasing.
H. The acceleration of the object is increasing.
