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 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 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 answer 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:
Potential energy is the energy an object has due to its position or state. In this case, since the book is at rest on a flat table, its potential energy remains constant as long as it stays on the table because its height above the ground does not change.
Kinetic energy, on the other hand, is the energy an object has due to its motion. When the person gives the book a shove, they transfer some energy to it, increasing its kinetic energy. The book starts moving and its kinetic energy increases.
As the book slides across the table, it experiences friction with the table surface, which gradually reduces its kinetic energy. Friction acts against the book's motion, converting its kinetic energy into other forms, such as heat and sound. Eventually, the book comes to rest again near the edge of the table, and its kinetic energy reduces to zero.
So, during this process, the potential energy of the book remains constant, while its kinetic energy increases when it is shoved and then gradually decreases as it slides and comes to rest.
