picking up a pile of books from the floor

When you hold a book, holding it in a stretched arm needs a lot of effort but does not involve much energy. If one manages to hold one stay perfectly steady the muscles cells don't need much energy.

  • In the scenario picking the book from the floor is a process of work done. As energy is transferred from one object by the application of a force.
