Question

What happens to the potential energy of a book that is dropped from a desk to the floor?

Answer 1

Answer:

D.   It is converted into kinetic energy.

Explanation:

When a book is dropped from a desk to the floor, the potential energy of the book is converted to kinetic energy as it falls.

• Potential energy of a body is the energy due to the position of the body.
• At a particular height, the potential energy is maximum.
• A body with mass and moving with velocity will have kinetic energy
• As the book drops through the height, to conserve energy, the potential energy is converted to kinetic energy.
