What kind of mechanical energy does a book lying on the table possess in relation to the surface of the table?

The kinetic energy of the book Ek is the energy of motion, because it is determined by the formula: Ek = m * V2 / 2, where m is the mass of the book, V is the speed of the book. Since the book is at rest, the speed of its movement is V = 0 m / s, and therefore the kinetic energy is also Ek = 0 J.

The potential energy of the book, which lies on the table, En is determined by the formula: En = m * g * h, where m is the mass of the book, g is the acceleration of gravity, h is the height of the body above the earth’s surface, that is, the height of the table. Since the surface of the table on which the book lies has some height h, the book also has potential energy.

Answer: the book on the table has only potential energy.
