understanding the relationship between sensor size and megapixels.

So as I'm shopping for my first new point and shoot in several years, I find myself wanting to understand the relationships between image sensors physical size and the total megapixels of that sensor better. Is there a loss in quality when you fit more pixels on a smaller sensor, or are you just gathering more light on the larger sensor.
I think this is another case where I may not know enough to ask the right question. Can anyone point me in the right direction to help get me started.
Thanks!
Nick
