Sarah wants to create an experiment to determine whether an object's weight determines how fast it will fall. She hopes to prove
that heavier objects fall faster than lighter ones. She buys two weights that have the same size and shape. However, one is heavier than the other. She has her mother drop both weights at the same time from a window. To her surprise, the weights land at exactly the same time. She repeats the experiment several times, but the weights always hit the ground at the same time. Sarah is forced to admit that she was wrong; an object's weight does not affect how fast it falls. A. "She has her mother drop both weights at the same time from a window."
B. "To her surprise, the weights land at exactly the same time."
C. "She hopes to prove that heavier objects fall faster than lighter ones."
D. "[A]n object's weight does not affect how fast it falls."
