kinetic energy
The book lying on a desk represents potential energy, specifically gravitational potential energy. When the book falls off the desk, the potential energy is converted into kinetic energy as the book moves downward due to gravity.
The normal force acting on a book sitting on a desk is equal in magnitude and opposite in direction to the force of gravity pulling the book downward. This force prevents the book from falling through the desk and is what keeps the book in place.
The book on the edge of the desk has potential energy due to its position relative to the ground. If the book falls, this potential energy will be converted into kinetic energy as it moves towards the ground.
The potential energy of the pencil is being converted to kinetic energy as it falls due to gravity.
A book bag on a desk has potential energy. That potential energy is due to its height above the ground. That potential energy is given by the formula Ep = mgh, where m is the object's mass, g is the acceleration due to gravity, and h is the height.

The energy involved is primarily gravitational potential energy. As the pencil falls, this potential energy is converted into kinetic energy.
No, a glass jar sitting on a desk is not considered potential energy. Potential energy is the stored energy an object has due to its position or state, such as a book on a shelf. The jar on the desk is not in a position where it can store energy in that way.
Every object in the world (and the universe which called Universal Gravity) is attracted to every other object by the force of gravity. That means the the desk and the book actually pull on each other. And the Earth pulls on both of them. The most important thing to consider is that the more massive an object is, the stronger its gravitational pull.That means that the Earth below the desk and the book pull on both these objects much more strongly than they pull on each other.The simple answer is that the Earth's gravity holds the book on the desk. But remember, the book is also pulling back on the Earth. They attract each other.
Kinetic energy is related to movement (a faster object has more kinetic energy); potential energy is related to position (higher up, objects have more potential energy).Examples:A leopard waiting in a tree, motionless, waiting to jump on you has potential energy.A leopard leaping on you has kinetic energy, or energy of movement.Kinetic energy is the energy that an object has when it is in motion. Potential energy is the energy that an object has when it is at rest. For example, a book sitting on a desk has maximum potential energy and zero kinetic energy. If the book falls off of the desk, then its kinetic energy increases and its potential energy decreases.
The Articles of Speech 'a' and 'the' have two separate meanings in English grammar. Using 'a' means, generally, any... for example: I saw a book on the desk. - This could be any book. But the desk is one particular desk. Using 'the' typically means one in particular. I saw the book on the desk. - Here, the book is a specific book. Consider these changes: I saw a book on the desk, but I can't say what it is about or even the title. I saw the book on the desk. It is the history class textbook, called "History and Today" by E.B. Smith.
Yes, generally speaking, the jobs represented at a help desk are similar to those offered by the customer service department. However, the help desk tends to be more helpful when you have questions of a more technical nature.
Either form of the prepositional phrase is correct, depending on the sentence; for example:The book is in your desk. I took the book from your desk and put it in the bottom drawer.
