Books Mechanics and Waves by Remington Pitts

A mechanical wave is a an oscillation of matter, and therefore transfers energy through a medium. While waves can move over long distances, the movement of the medium of transmissionthe materialis limited. Therefore, the oscillating material does not move far from its initial equilibrium position. Mechanical waves transport energy. This energy propagates in the same direction as the wave. Any kind of wave (mechanical or electromagnetic) has a certain energy. Mechanical waves can be produced only in media which possess elasticity and inertia. Mechanics is the study of the motion of matter and the forces required to cause its motion.
