Answer 2

$\mathfrak{\huge{\green{\underline{\underline{Answer :}}}}}$ When an object vibrates, it doesn't move permanently out of position. ... But an object in vibrational motion wiggles about a fixed position - its original equilibrium position. Because of the restoring force, vibrating objects do the back and forth.
