When a book is picked up,its potential energy is increased. The hand picking up the book is also gaining potential energy. The energy is coming from the muscles contractions involved in picking up the book. The muscle energy is a result of processing food nutrients.
Of corse,potential energy of pencil is increased.Therefor work done
I pick up the large pieces by hand, then sweep everything I can into a dustpan. After that I run the vacuum over the area.

The pencil would just slide out of your hand because there would be nothing holding it there. You would have to balance the pencil on your hand!
Sharks and rays have very low metabolic rates. This allows them to pick and choose their food, and wait a long period of time between meals.
transfering the kinetic energy in your hand to the book
When you pick up a book, the energy transfer primarily comes from the muscles in your hand and arm that move and lift the book. The lifting action requires energy to overcome gravity and support the weight of the book.
The book gains potential energy when you pick it up off the floor. This potential energy is stored in the book's position above the ground and can be converted into kinetic energy if the book is dropped.
Kinetic energy
Yes, you are transferring to kinetic energy!
Slaves pick cotton by hand.
The scientific definition of work is using force to move an object over a distance. When you use your hand to lift the book off the floor, you are going against the force of gravity that is attracting it to the floor in order to lift the book in the air, from one location to the next. However, when you carry a book across the room, you are not fighting a force. As a matter of fact, the book has not left your hand; therefore, you are not moving it anywhere. The tricky thing is to not think of of the book as moving across the room - YOU are moving across the room; the book is still sitting in your hand. Now, if you THROW the book across the room, that is different entirely.

When strumming a guitar, mechanical energy from the motion of the player's hand is transformed into sound energy as the strings vibrate and produce sound waves. Additionally, some of the mechanical energy is also transformed into thermal energy due to friction between the strings and the pick or player's fingers.
