4. Eddie drops a heavy book onto the floor. What does the energy of the book turn into when the book hits the floor?
Furkat [3]

Answer:

Heat and sound energy

Step-by-step explanation:

It starts off as potential energy, which is then converted to kinetic energy and by impact it'll develop a sound and heat energy.

Sound waves generates heat, and if some glass fell on the floor you can heat the shatter from the sound waves. The same goes for a book.
