Fast and quick

[Unregistered]

Hi,
I would like to know what is the exact difference between Fast and quick?
Thank you very much for you help.

They mean the same, so the differences are collocational; we would, for instance, generally talk about a fast car, but in a race you could say that a car had been quick, which would imply that it had reached a high speed on this occasion rather than always doing it.
