Item NG079002: The motion energy of a book sliding across a table is transformed into thermal energy, not into a force.
A girl shoves a book, and it slides across a table. The book slows down and then stops. As the book moves, the book and the table get a little bit warmer. What happened to the motion energy (kinetic energy) of the book?
- It was transformed into a force but not into thermal energy.
- It was transformed into thermal energy but not into a force.
- It was transformed into both a force and thermal energy.
- It was used up and was not transformed into a force or thermal energy.
