TASK DEFINITION: You are given a paragraph, with numbered sentences, and a question. Write the numbers of the sentences needed to answer the given question. Separate multiple sentence numbers with a comma (", "). E.g. "1, 2" would be the correct response if Sent 1 and Sent 2 are needed to answer the given question (do not include sentences that contain no information that is necessary to answer the question). Sort the sentence numbers in an increasing order (i.e., '1, 2', instead of '2, 1'). Your answer should not contain anything than the sentence numbers separated by a comma (e.g. '1, 2, 3, 4'). The given question requires more than one sentence to answer. So, your answer must contain at least one comma (", ").

Sent 4: When work is done, energy is transferred.
Sent 5: This transfer occurs between one object and another.
Sent 6: For example, a batter swings a bat and transfers energy.
Sent 7: She transfers her energy to the bat.
Sent 8: The moving bat, in turn, transfers energy to the ball.
Sent 9: Energy is measured in the Joule (J).
Sent 10: Energy exists in many forms.
Sent 11: One form of energy is called mechanical.
Sent 12: Mechanical energy is the energy of motion.
Sent 13: This type of energy can also include things that are not yet in motion.
Sent 14: In these cases, they have only a potential to be in motion.
Sent 15: In most cases, this ability comes from a position.
Sent 16: A rock sitting on top of a cliff has potential energy.
Sent 17: It is more than just the ability.
Sent 18: A rock sitting on the ground could move if someone picked it up.
Question: Describe potential energy and give an example.
