THe damping factor coefficient:

$=\frac{}{2m}$

Frequency can be expressed in terms of the spring constant $k$ as:

$f=\frac{1}{2}\sqrt[\phantom{2}]{\frac{k}{m}}$

Assuming X and k are independant of the mass $($m$),$ how would you expect the damping factor and frequency to change as a result of increasing mass?
