Nothing can move with out energy‚ and the energy of movement is kinetic. The book on the shelf had to be placed in that position and the soda machine had to be stocked. The weight of the book‚ the force‚ and the distance of the shelf‚ and all of the motions needed to reload a soda machine equals work. W=Fd. The work it took to load the soda can‚ created
