Which of the following claims and evidence correctly describe the relationship between the height from which you drop a clay ball and the amount of energy it has when it hits the ground?
A. The higher the drop height, the more energy it has. The evidence that proves this is that the clay ball barely changes it's shape when dropped from higher feet.
B. The lower the drop height, the less energy it has. The evidence that proves this is that the clay ball barely changes it's shape when dropped from higher feet.
C. The lower the drop height, the less energy it has. The evidence that proves this is that the clay ball flattens out more when it's dropped from higher feet.
D. The higher the drop height, the more energy it has. The evidence that proves this is that the clay ball flattens out more when it's dropped from higher feet.
D. The higher the drop height, the more energy it has. The evidence that proves this is that the clay ball flattens out more when it's dropped from higher feet.
