Vibratory motion of ideal systems in the absence of any friction or resistance continues indefinitely under the action of a restoring force. Practically, in all systems, the force of friction slows down the motion, so the systems do not oscillate indefinitely. The friction reduces the mechanical energy of the system as time passes, and the motion is said to be DAMPED. This damping progressively reduces the AMPLITUDE of OSCILLATION.

What is the basic function of insulation?
Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.
What is the effect of temperature on dielectric constant of a dielectric?
Usually, dielectric materials have permanent dipoles. As temperature increases, the molecules in the dielectric have more thermal energy and therefore, the amplitude of random motion is greater. This means that the molecules are less closely aligned with each other (even in the presence of an electric field). Hence, the dielectric constant reduces.
When the length of air gap is increased in an induction motor what will also increase?
Power factor reduces overload capacity increased noise reduces
How do you reduces ac no lode current in transformers?
Disconnect the primary source.
A countermeasure is anything that effectively reduces an adversary and ability to exploit our vulnerabilities?
True
How damping progressively reduces the amplitude oscillations?
When energy is lost from the oscillating system, the amplitude of oscillationdecreases. When that happens progressively, we say that the oscillation is"damped". "Damping" is a description of the decrease, not its cause.
How is light damping achieved?
The amplitude of resonant oscillations can be reduced by damping.Light damping reduces oscillations slowly.Heavy damping reduces oscillations quickly.Critical damping stops the oscillation within one cycle.The graph above shows light damping.
How does destructive affect the amplitude of a wave?
It reduces amplitude.
How does destructive interference affect the amplitude of a wave?
Destructive interference affect the amplitude of a wave because two identical waves with similar amplitude and wavelength, arrive in anti phase, leading to a zero displacement.
What is the basic function of insulation?
Heat insulation reduces the rate of heat flow. Sound insulation reduces the amplitude of the sound energy transmitted through a cavity.
What is the function of an attenuator in cro?
An attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. attenuator just decrease its amplitude and the attenuator you can take it as a opposite of amplifier. Amplifier just modifies the input signal gives amplified output signal
How High pass filter circuits works?
A High Pass Filter is an Electronic Filter that passes high frequency signals but Attenuates (reduces the Amplitude ) of Signals with frequencies lower than the cut-off Frequency
What is the purpose of the voltage divider control in oscilloscope?
This control reduces the amplitude of the applied signal to a point where the whole signal can be displayed on the oscilloscope screen. The amount of voltage reduction is marked on this control switch so that it can be used as a voltmeter.
Show how the period of oscillation relates to the velocity of the pendulum bob.?
Technically, in an ideal experiment, where there is lack of any opposing forces like air drag and friction, the period of oscillation of a pendulum only depends on the length of string (i.e, for r<<L). However, in presence of air drag, a force opposite to the velocity of the bob reduces the energy of oscillations, so it also changes the period of oscillations. acc to a law similar to stoke's law Fv = -bv where 'b' is a constant and depends on medium and the bob. So, the force acting on bob is the resultant of -w2x and -bv. this is how the period of oscillation depends on the velocity of pendulum bob.
What are attenuators?
attenuator (disambiguation)An attenuator has three distinct meanings:* attenuator (electronics) is an electronic device that reduces the amplitude of a signal* attenuator (genetics) refers to specific regulatory sequence transcribed into RNA* impact attenuators are used on highways as a crumple zone in case of a car crash.Above retrieved from Answers.comViper1
