Basic physical terms related to sound Acoustics: Study of sound Sound: Mechanical wave created by a vibrating object. Vibration: The movement of an object from one point in space to another and back to the initial state. http://www.physicsclassroom.com/Class/sound/U11L1a.html http://www.physicsclassroom.com/mmedia/waves/lw.html

Factors related to vibration Inertia “The tendency of a body to maintain a state of rest or uniform motion unless acted upon by an external force.” Elasticity “The ability of a body to return to a starting state after it has been deformed or moved by a force”. Damping “Resistance to motion”
