Question

Steven holds a book above the floor. He lets go of the book and the book speeds up as it falls to the

floor. Which of the following forms of energy are involved in an energy transformation while the book is
falling?
А
Both potential energy and kinetic energy are involved. As the book is falling, its potential energy
decreases and its kinetic energy increases.
B
Kinetic energy is involved but potential energy is not. As the book is falling, its kinetic energy
increases but its potential energy does not change.
C
Potential energy is involved but kinetic energy is not. As the book is falling, its potential energy
decreases but its kinetic energy does not change.
Neither potential energy nor kinetic energy is involved. Potential energy cannot be changed into
kinetic energy, and kinetic energy cannot be changed into potential energy

Answer 1

А

Both potential energy and kinetic energy are involved. As the book is falling, its potential energy

decreases and its kinetic energy increases.
