As you lift a book into the air Gravitational potential energy will increase in the book.
Answer: Option C
Explanation:
Gravitational potential is referred as the energy spent to move the mass from one point to another. The formula is m * g * h. When a book is lifted, there is a change in position, therefore the gravitational potential energy used is increased because the gravitational force is acting upon the object (i.e) the book. Option A,B, and D are invalid in this situation.
