Just as disturbing only one strand affects the whole web, so do our actions. How the web is affected is determined by whether our actions are good or bad.
The idea is that because it is your actions that create the world you have to live in, "you should be the change you want to see in the world".
I think its not quite so equal and opposite as Newton's laws... and I think a buddist would at least be uncomfortable with Karma being explained so scientifically, but the rest of your explaination is very good I think. Maybe its like the chaos/ripple in the pond kind of principle mixed with Newton's third law... kind of.
