dauto said:Vibration is when different parts of an object oscillate in tandem forming waves that propagate through the body.
AlephZero said:If that is the definition from some reference source, fine (but it would be nice to know the source).
But I would define vibration in a more general way, as any type of motion of an object around some equilibrium position. Not necessarily periodic, and not necessarily forming anything that looks like "waves". For example "random vibration" is certainly used in engineering to describe motion that can only be described and analyzed statistically.
abi.ayan said:what is the difference between vibration, oscillation,simple harmonic motion and periodic motion?Is there any similarities between these terms? can anyone explain clearly pls.
Vibration refers to the rapid back-and-forth motion of an object around its equilibrium point. It can be caused by an external force or by a disturbance in the system.
Oscillation refers to the repetitive movement of an object around its equilibrium point, where the object returns to its starting position after each cycle. It can also be caused by an external force or disturbance.
Vibration and oscillation are different in terms of the types of motion they involve. Vibration involves a rapid back-and-forth motion, while oscillation involves a repetitive movement around an equilibrium point. Additionally, vibration can be caused by an external force or disturbance, while oscillation can occur without any external force.
Yes, vibration and oscillation can occur simultaneously. In fact, oscillation can be seen as a type of vibration, but not all vibrations involve oscillation.
Vibration and oscillation have various real-world applications. Vibration is used in musical instruments, engines, and electronic devices, while oscillation is used in timekeeping devices such as clocks and pendulums. They are also used in medical equipment, such as ultrasound machines, for diagnostic purposes.
