Question

explain free oscillations and resonance

Answer 1

Hey mate !



▪ Free Oscillation : An oscillation of a body or system with its own natural frequency and under no external influence other than the impulse that initiated the motion is called also free vibration is opposed to forced oscillation.


▪ Resonance: The increase in the amplitude when the driving force is close to the natural frequency of the oscillation is called resonance.

Answer 2

$\mathfark{FORCED\: OSSILATIONS\: AND\: RESONANCE; }$

$\mathbb{FREE \:OSCILLATIONS: }$
$<b><I>$
whenever a system is disturbed from its equilibrium configuration it oscillates with the frequency which is characteristic of the geometry and inertia of the system such oscillations are called as free oscillations

$\mathbb{FORCED\: OSCILLATIONS; }$

whenever system is free oscillation is subjected to an external periodic force the system vibrates not with its natural frequency but it is a frequency of the external force such oscillations are called as forced oscillationl.

$\mathbb{RESONANT\: OSCILLATIONS; }$

when the frequency of the applied force is equal to the natural frequency of the system the system vibrates with very large amplitude such oscillations are called as resonant oscillations and the phenomenon is called as resonance .
