When a body vibrates under a periodic force, the vibrations of the body are : (a) natural vibrations (b) damped vibrations (c) forced vibrations (d) resonant vibrations. Q. what is natural vibration, forced vibration, and resonance? Q. What is the difference between free and forced vibrat...
such as if the vibrations are “damped” slow down due to friction. This type of system is more applicable in the real world – for instance, a guitar string will not keep vibrating indefinitely after it has been plucked.
While go through the topic vibrations in longitudinal and transverse beam in Civil Engineering, I came across a term 'Damping'. I want to know what is damping, how the damping factor is defined. Please explain with some suitable examples. ...
Unit of Vibration Vibration is a term that tends to induce the sound when someone hears it. Everything in the world vibrates invariably. Some vibrations are good and useful, some are tolerable while some fall under the dangerous category. One of the examples of good vibration is a vibrating...

What are damped vibrations? How do they differ from free vibrations? Give one example of each. Give 3 examples of applications of the conservation of angular momentum. Give an example from classical physics in which the motion of a clock affects its rate-that is the way it runs. (The magn...
Crystals are piezoelectric devices, meaning that mechanical vibrations that change the shape of the crystal occur when electrical charge is applied to them and vice versa. Crystals are predominantly made using quartz, so they are commonly referred to as quartz crystals or quartz crystal resonators. ...
On the basis of characteristics of particle vibration: If the particles of a medium vibrate simple harmonically, the corresponding wave is called simple harmonic wave. Practically most waves are produced by complex vibrations. But any complex wave may be described as superposition of a number of si...
