Document Summary
Nearly every object can be set into vibration. Some objects are set into vibration more easily than others ex. tuning fork vs wall. The tendency of a system to vibrate with greatest amplitude in response to a frequency that matches or comes close to its own natural frequency pg 45. The rate at which an object vibrates when it is set into motion. This will depend on length, density, tension, and stiffness. What the object is made of affects speed. The frequency/set of frequencies that the object prefers". Something set into forced vibration by another vibration. Vibration caused by an external force (ex. vibration from one object causes. Occurs through shm (if close enough) and also when the rfs of two objects. Free vibration: object vibrates at a rate that is predetermined by its length, mass, tension, stiffness (natural resonant frequency)
