Difference between polarity and phase w/sub

In my Anthem AVM20 setup menu there are adjustments for polarity (normal and inverted) and phase (0-180) for the subwoofer output. When I change one or the other it seems to make the same difference. Can anybody give me an explanation of the difference between the two? I have an idea but just want to be sure.

Thanks,

Thanks for the replies. Thanks Herman for the indebt definition of phase. I knew that inverting polarity means to switch the positive and negative lead, but was not sure about phase.

Herman:

If my sub is located between the main speakers but is about 3 feet behind them, how should I set phase?
