| Abstract: | The movement of media elements can be analyzed according to the varying of density of media when the longitudinal wave is propagating through it.Based on the relationship of the inner force in a media and its movement,it can be proved that the inner force intensity in a media is simply equal to the energy flow density. |

| Keywords: | longitudinal wave movement of media elements energy flow density |
