CORRECT ANSWERS
The amplitude of the oscillations decreases gradually (but the time period is the same
as its independent to amplitude) - CORRECT ANSWERwhat happens in a lightly
damped system
the system returns to equilibrium in the least time possible
a mass-spring system in cars - CORRECT ANSWERwhat happens in a critically
damped system and give an example of it
the system returns to equilibrium in a long period of time
a mass-spring system in oil - CORRECT ANSWERwhat happens in a heavily damped
system and give an example of it
the amplitude of vibration of an oscillating system subjected to a periodic force is largest
when the periodic force has the same frequency as resonant frequency of the system -
CORRECT ANSWERwhat is resonance
the frequency of an oscillating system in resonance - CORRECT ANSWERwhat is
resonate frequency
the frequency of free oscillations of an oscillating system - CORRECT ANSWERwhat is
natural frequency
vibrations (oscillations) where there is no damping and no periodic force acting on the
system, so the amplitude of the oscillations are constant - CORRECT ANSWERwhat is
free vibrations
vibrations (oscillations) of a system subjected to an external periodic force - CORRECT
ANSWERwhat is forced vibrations
a force that varies regularly in magnitude with a definite time period - CORRECT
ANSWERwhat is periodic force
the amplitude increases to a maximum once it reaches resonant frequency, then
decreases as applied frequency exceeds resonant frequency - CORRECT
ANSWERwhat happens to amplitude as applied frequency (a periodic force) increases
