A book is at rest on a flat table. A person gives the book a shove and it slides across the table. The book eventually comes to rest again near the edge of the table. How does the potential and kinetic energy change during this process?(1 point) Responses The potential energy will stay the same as long as the book stays on the table. The kinetic energy increases when the book is shoved and then gradually decreases as it slides across the table and then comes to rest on the edge. The potential energy will stay the same as long as the book stays on the table. The kinetic energy increases when the book is shoved and then gradually decreases as it slides across the table and then comes to rest on the edge. The potential stays the same since the book is on the table. The kinetic energy stays the same since the book was only shoved. The potential stays the same since the book is on the table. The kinetic energy stays the same since the book was only shoved. The potential energy increases as the book is pushed across the table. The kinetic energy stays the same since the book was shoved. The potential energy increases as the book is pushed across the table. The kinetic energy stays the same since the book was shoved. The potential and kinetic energy are the same while the book is sitting on the table. They both increase when the book is shoved and then decrease as the book comes to rest again.

Answer 1

The correct understanding of the changes in potential and kinetic energy during the process described would be:

• The potential energy will stay the same as long as the book stays on the table, because its height above a reference point (the table) does not change.
• The kinetic energy increases when the book is shoved, as it gains speed from the applied force, and then it gradually decreases as friction and other forces (like air resistance) act on it while sliding across the table until it comes to rest.

So, the best response would be: "The potential energy will stay the same as long as the book stays on the table. The kinetic energy increases when the book is shoved and then gradually decreases as it slides across the table and then comes to rest on the edge."
