A book, no matter where it sits, is an organized and bound assembly of paper with
information stored on it.
The book has some mass, and like any mass, its gravitational potential energy relative
to the floor can be defined in terms of its mass and its distance above the floor.
YES!
No. The potential energy of an obect also depends on its mass.
Potential energy.
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
YES!
Place it on a higher shelf. If it has to stay on the same shelf, then its potential energy can only be increased by adding some pages to it.
put the book higher up on the shelf
No. The potential energy of an obect also depends on its mass.
Gravitational potential energy
Potential energy.
The potential energy of the book on the shelf is equal to the work done to lift the book to the shelf. This is because the potential energy of an object at a certain height is equivalent to the work done against gravity to lift it to that height.
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
a book sitting up on a shelf. gravity can potentionally pull it down if pushed.
There is no direct relationship because the potential energy of the book on the shelf is defined relative to an arbitrary base line at which the potential energy would be zero. The work done in raising the book is the increase in the potential energy of book from however much PE it had in its previous location - for example, on a lower shelf.
When a book is falling from a bookshelf, it is in a state of kinetic energy because it is in motion. Potential energy arises when the book is stationary on the shelf due to its height above the ground.
It has mechanical energy. The exact type of energy is potential.
