Sure you can. Spin it at 100 RPM, or 1000, RPM or even 25000  RPM... :)

Interesting conversation. I tend to agree the earth is not a classic 
harmonic oscillator. Energy is not exchanged between different storage 
mechanisms. It's rotational period has no natural harmonic frequency. 
i.e. rotational period could be anything.

However I also agree it exhibits characteristics of other items that Q 
can be calculated for. Rate of slowing, loss of energy per cycle, etc.
And since the definition of Q is varied and used quite widely, it seems 
Q is also appropriate here.

Maybe Earth is a special case since after all it DID give us the second, 
and we DO set our atomic clocks to IT every 6 to 12 months...

...now I'll be thinking of this all night...  ...I think Tom is just 
toying with us now...
