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)

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 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 increases as the book is pushed across the table. The kinetic energy stays the same since the book was shoved.

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.

Here's the reasoning:

• Potential Energy: As long as the book remains on the flat table, its height relative to a chosen reference point does not change, so the potential energy remains constant.
• Kinetic Energy: When the book is shoved, it gains kinetic energy due to the force applied to it, causing it to move. As the book slides across the table, it gradually loses kinetic energy due to friction acting against its motion, and eventually comes to rest at the edge of the table.
