Question

An Apple On A Tree Has More Energy Than A Book Lying On A Table. Give Reason?

Answer 1

Yes, there are forces acting on the book. 
If the book is kept on a flat table then the forces acting on the book are Balanced in nature. 
The weight of the book(=mg) acting downwards and the Normal Reaction acting upwards. The balanced nature of these 2 forces causes book to stay still on the table!
