Scientific Explanations – Evaluating an explanation for accuracy
Second explanation to evaluate:
(1) After the kick there is a contact push/pull interaction between the ball and ground. (2) There is a transfer of energy between the ball and ground. (3) Both the kinetic energy and the thermal energy of the ball decrease, while the thermal energy of the ground increases. (4) Because the kinetic energy of the ball decreases, it slows down.
This explanation is...
A) Accurate as written.
B) Not accurate because sentence #1 is not correct.
C) Not accurate because sentence #2 is not correct.
D) Not accurate because sentence #3 is not correct.
E) Not accurate because sentence #4 is not correct.
F) Not accurate because more than one sentence is not correct.
Feedback: This explanation is not accurate because sentence #3 is wrong (choice D). The thermal energy of the ball does not decrease; it increases.
