Swinging Damage

So swinging is a sperate feature but can it be used for damage? For example if I swing acorss the map and kick a villain it would seem that would be greater than your typical melee attack? Would I take my character's weight and adjust as if I were "thrown" at the villain? 

Also I do not have the rules in front of me right now but in the comics I believe it is mentioned that Quicksilver enjoys a hefty momentum bonus to punching when in motion. Does super speed add anything to melee?
