Quizplus · Accepted Answer

The kinetic energy of an object increases with its velocity, and since the object is falling from rest, its velocity will continuously increase until it reaches a terminal velocity due to air resistance. Therefore, the curve should start with a low kinetic energy and gradually increase until it levels off at the terminal velocity. Choice C) represents this behavior the most accurately.
