Define damped oscillation?
Any oscillation in which the amplitude of the oscillating quantity decreases with time is referred as damped oscillation. Also known as damped vibration, http://www.answers.com/topic/damped-harmonic-motion
Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
Oscillation that increases without limit. Eventually it will destroy things.
It is damped oscillation.
Oscillations (vibrations) are damped when they are changed by some action. For example, touching an oscillating (vibrating) tuning fork with your finger is said to be damping it. The oscillation (number of Hertz) of an electrical oscillator, such as a TV tuner, is changed by varying the settings of the tuner.
When energy is lost from the oscillating system, the amplitude of oscillation decreases. When that happens progressively, we say that the oscillation is "damped". "Damping" is a description of the decrease, not its cause.
Yes. You can have damping, independently of whether there is resonance or not.
It means the oscillations lose energy over time, getting weaker and weaker.
The motion of swinging is an example of forced, damped oscillation. A more simple form of this is simple harmonic oscillation and can be read about here: http://en.wikipedia.org/wiki/Simple_harmonic_motion
what do you mean by terms under damped, critical damped and over damped frequency of control system?
Forced vibration: If a system is subjected to an external force, the resulting vibration is known as forced vibration if the frequency of the external force coincides with one of the natural frequencies of the system, a conditions known as resonance occurs (large oscillation). Failures of such structures as building, bridges, turbines and airplane wings have been associated with the occurrence of resonance. Damped vibration: Ifanyenergy is lost or dissipated in friction or other resistance… Read More
What are the applications of oscillatory motion in technology or where can the applications of oscillatory motion be seen?
the car tire....damped oscillation How about a speaker? When you apply signal to it, the cone oscillates in and out.
(Amplitude)at time=t = (Max) x cos[ (2 pi x frequency) + (phase angle) ] x e-time/time constant
damped vibrations: in damped vibrations the amplitude of the signal decreases with respect to time undamped vibrations in undamped vibrations the amplitude of the signal remains constant with respect to time

Answer #1: Some ways to increase the velocity of a simple pendulum are forced oscillation and damped oscillation. ============================ Answer #2: But the more common and conceptually much easier ways are to decrease its length or move it to a place where the acceleration due to gravity is greater. Also, although it's usually ignored, the period does become shorter as the width of the swing decreases. This really isn't relevant right now because, although you… Read More

It is usually damped harmonic motion.
Oscillations are reoccurring and regular fluctuations between particular states within a system. These states could be discrete, such as a car's turn signal blinking on and off; continuous, such as a wave; damped, such as the gradual decay of the amplitude of a vibrating guitar string; or driven, such as the forced motion of someone on a swing. The states involved in an oscillation don't have to just be mechanical in nature. For example, the… Read More

Resonance is a force that remains in a opposite position.It is also observed in physical media such as strings and columns of air. Any waves traveling along the medium will reflect back when they reach the end. It is possible to have damped oscillations when a system is at resonance.
it will occur just before the resonance.

With respect to an RLC circuit, the critical resistance is the resistance which would critically dampen the circuit. This means a resistance lower than the critical resistance would create an under-damped situation, and higher than the critical resistance would create an over-damped situation. An underdamped circuit will ocillate, an overdamped circuit will decay exponentially over a long period of time. The critically damped circuit will immediately decay to zero (time dependent on the values of… Read More

The simple harmonic motion is a special case of vibration, which is neither damped, nor driven and can be described by a sinusoidal function.
The answer will depend on what b and k are! And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.

The magnetic field diverts most positive charges of the solar wind to the south pole, and "scoops" more solar wind than Earth would otherwise receive. Much of these positive charges are hydrogen, the hydrogen oxidizes to water vapor, and water vapor both prevents one method of making ozone and accelerates the decay of ozone. So the magnetic field makes the south polar hole larger than the north polar hole, and serves to deplete ozone generally… Read More

A (non digital) speedometer is a damped needle moved by a rotating magnet driven by cable from either the gearbox or one of the wheels.
Aerodynamic Flutter is usually applied to wings or ailerons and is the unstable oscillation caused by interaction between aerodynamic forces, elastic reactions in the structure and the force of inertia. Unless damped quickly flutter will break a wing. The cure for flutter is usually to dispose the weights so that the centre of gravity of the wing is as far forward as possible. Ailerons, elevators and rudders are mass-balanced to prevent flutter. Flutter is a… Read More
We find that isolators that are incorporated into structures allow that building to move independently of the ground. This construction strategy permits the energy of the quake to be damped by the isolators, and this reduces the damage done to the structure.
