no, but the POTENTIAL energy may equal the work done to life the book to the shelf
Potential energy.
YES!
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.
Potential Energy If it falls, it will then be subject of gravity, so it has the potential of becoming energetic. -------------------- The bookshelf could also catch fire and the book would release energy as heat.
Yes it is. Because it has the POTENTIAL of falling off. Very simple physics, learned that in 6th grade.
no
false
A book on the bottom shelf usually has more kinetic energy because it has the potential to fall from a greater height than a book on the top shelf. As an object falls, its potential energy is converted to kinetic energy.
Kinetic Energy
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.
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.
When a book falls off a shelf and hits the ground, its potential energy is converted to kinetic energy as it falls. When it hits the ground, some of the kinetic energy is converted into sound and heat energy due to the impact.
Before it falls it has gravitational potential energy. While it falls, the potential energy gets converted to kinetic energy. Part of this gets dissipated by friction - mainly converted to heat. Once it hits the ground, all the energy will be converted to heat.
The total mechanical energy of the book falling off the shelf is the sum of its potential energy and kinetic energy. Therefore, the total mechanical energy is 110 J (50 J potential energy + 60 J kinetic energy).
The book has kinetic energy as it falls towards the floor. When it hits the floor, some of this kinetic energy will be converted into sound energy and some into thermal energy due to the impact.
The potential energy of a book on a bookshelf is due to its position above the ground. When the book is lifted or moved from the shelf, the potential energy decreases as it is converted into kinetic energy.
