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 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.

The potential stays the same since the book is on the table. The kinetic energy stays the same since the book was only shoved.

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.

Explanation:

• When the book is at rest on the table, its potential energy is constant as long as the height does not change (the book remains on the table).
• As the person shoves the book, kinetic energy increases due to the force applied, and the book starts to move.
• As it slides across the table, the kinetic energy gradually decreases due to friction (or any other opposing forces) until it comes to a rest again.
• The potential energy remains unchanged throughout this process since the book is not changing its height.
