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 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 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 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 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.
To understand why this is the correct answer, let's break it down:
When the book is at rest on the table, it has potential energy due to its position above the ground. However, since the book is not moving, it does not have any kinetic energy.
When the person gives the book a shove, they impart an external force on the book, causing it to move. As the book slides across the table, its potential energy remains the same because it is still on the table, at the same height. The kinetic energy of the book increases because it is now in motion.
However, as the book comes to rest again near the edge of the table, its kinetic energy gradually decreases. This is because the external force that was initially applied to the book stops acting on it, and other forces such as friction and air resistance slow it down. Eventually, the book comes to a complete stop, and its kinetic energy becomes zero again.
So, in summary, during the process of the book sliding across the table and eventually coming to rest, the potential energy remains the same, while the kinetic energy increases and then decreases.
