Tell how energy is transferred to the building where the heater is located

A book is sitting on a shelf that is 3.0 meters off the ground. Kinetic energy is found using the formula 1/2 times mass times speed. Potential energy is found by taking mass times g times height, with g as the constant, 9.8 m/s squared.
