Abstract

For undergraduate students who study physics, engineering or science. One important elementary example of the basic properties of waves is studies the oscillation of the mechanics of the wave. In physics, wave is an oscillation accompanied by a transfer of energy that travels through space or mass. In this research, we will focus on the oscillation of the mechanics of longitudinal waves which, oscillation is parallel to the direction of energy propagation. The mechanical of longitudinal waves propagate via molecules of medium colliding with their neighbours. When molecules of medium collide, they bounce away from each other (a restoring force). This keeps the molecules of medium from continuing to travel in the direction of the wave. The purpose of this research is developing a formalism based on the actual physical process of mechanical of longitudinal waves. By using technique of discrete element method (DEM). DEM is very closely related to molecular dynamics. This numerical method is computing the motion and effect of interaction between particles. Our main result shows that the consistency to the actual physical process in general explanation of mechanical of longitudinal wave.
