Question

what is the relationship between the work done while moving a book to a higher bookshelf and the change of potential energy? multiple choice the potential energy increase is greater. the work done is greater. there is no relationship between work and potential energy. the increase equals the work done.

Explanation:

According to the work - energy theorem, when moving a book to a higher bookshelf in a conservative force field (like the gravitational field near the Earth's surface), the work done against gravity is equal to the change in the book's gravitational potential energy.

Answer:

D. The increase equals the work done.
