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.
Lying on a desk: Potential energy Falling off a desk: Kinetic Energy
kinetic energy
If i am thinking correctly, the answer is physical energy, only because you are putting actual force.
The force of your pencil or pen against the desk that your paper is on if you're writing something down. The force of your paper against the desk. The force of your book against the desk. In each case, the desk exerts the identical but opposite force against the object lying on it. If that were not true, the objects would deform the desk, or the desk would form a bump where the objects are lying on it.
Yes, there are many examples. Electrical energy to light energy (light bulb). Mechanical energy to heat energy (rub your hands together). Chemical energy to light energy (a glowstick), and on and on.

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.
The plural form for the pronoun 'it' is 'they' for the subject and 'them' for the object of a sentence or clause; fro example:There is a book on my desk, it is a math book.There are books on my desk, they are math books.There are books on my desk, I just bought them.

Desk to Desk Courier
The possessive noun for a desk belonging to one student is "student's desk." If the desk belongs to multiple students, it would be "students' desk." The term "students desk" without an apostrophe implies a desk for students in general rather than a specific student or group of students.

The full form of DTDC is "Desk to Desk Courier".
The force of your pencil or pen against the desk that your paper is on if you're writing something down. The force of your paper against the desk. The force of your book against the desk. In each case, the desk exerts the identical but opposite force against the object lying on it. If that were not true, the objects would deform the desk, or the desk would form a bump where the objects are lying on it.
by putting energy into a molecule ------------------------------------------------------------- Energy is mainly of two form. One is matter and the other is radiation. Due to radiation such a photon energy would be given to a molecule. That energy will be stored within the molecule in the form of electromagnetic fields and mechanical too. Sometimes fast moving material particles with their mechanical energy would energize a molecule. That too will be stored in the form of electric or magnetic or mechanical form.
How does a book on a higher shelf have more potential energy than a book on the lower shelf
