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)

Question

Responses

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.

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.

Answer 1

The correct response is:

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.

This explanation accurately describes the changes in potential and kinetic energy during the process. While the book is on the table, its potential energy remains constant since the height hasn't changed. When the person shoves the book, its kinetic energy increases as it gains speed, and then it gradually decreases due to friction until it comes to rest.
