Newton tells us that, “A moving object [eg, a rugby ball – my example, not Newton’s.] As spring blooms, every club team in the north is fighting to harness the centre piece of Newton’s law of inertia. No defensive system works if players miss tackles and recently the Munster players seem to think that tackle is what you take fishing. Unlike Newton’s law of inertia, in rugby, momentum works both ways.
