What happen to the kinetic energy of a falling book when the book hits the floor?

Answer 1

when book is dropped from the height its kinetic goes on increasing and the sudden stop to the book when it touches the ground all the kinetic energy of the book is converted into potential energy of the book which helps the book to be stable after the impact, in short when the book hits the ground kinetic energy is converted to potential energy due to law conservation of energy.

Answer 2

I"m not sure why this question is here instead of Physics, but a book on a table has potential energy. The book falling off the table (i.e., in motion) has kinetic energy.
