A hob is a shelf at the side or back of a fireplace.
Bookshelf.
A hob.
empty bookshelf
Help me find that out
no, but the POTENTIAL energy may equal the work done to life the book to the shelf
no
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.
Picking up the box gives it kinetic energy. When the box is sitting on the shelf, it has potential energy.
Gravitational Potential Energy, also known as GPE.
Well, the energy might be stored in a brick sitting on a shelf and when you drop it that energy is turned into kinetic energy. When the brick hits he ground the kinetic energy might be used to break it up into pieces.
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.
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.
Potential energy. If the vase falls, it is converted to kinetic energy. A good article is in the link below.

Yes; while on the shelf it has potential energy due to gravity of mgh where m = mass and g =gravity acceleration and h is height fom floor. As it falls its potential energy is converted to kinetic energy mv squared/2 where v = velocity
