impedance/resistance
The Q factor of a coil, sometimes called the unloaded Q factor, is the ratio of the energy stored in the coil to the energy dissipated in the resistance of the wire.
In a RLC series circuit the Q factor magnify the voltage to the circuit.
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
yes ,Q factor is ratio of energy stored to energy dissipated

Q is the general idea of component quality, mainly in AC circuits. It is equal to reactance divided by resistance. The Q factor of an entire circuit can also be computed the same way. In general, adding resistance decreases the circuit or component Q. The "Q" factor is a empirical number to imply the acuteness of a circuit to discriminate surrounding influences and act on the Q of the circuit. The higher the Q THE SHARPER THE RESPONSE.

Q is often used to connote "electric charge".The Q factor of tuned circuits is a measure of "quality factor". It is a measure of how well the tuned circuit selects wanted frequencies and rejects the unwanted.
Minimize circuit resistance.
8(p + q)(p^2 - pq + q^2)
Sharp tuning the bigger the Q the sharper the response
