Introducing THE COSINE FACTOR – a simple yet never-before-considered Concept in Golf … Special report by Kiran Kanwar.
Stand on a driving range inhabited by professional golfers – anywhere in the world, any tour, and what do they all do? Move their arms (and therefore club) WAY inside the target line immediately past impact. This constitutes one of the many “what sense does that make” questions one should, but does not, ask in golf.
Why does the club move way inside the target line? Because the trail shoulder is way forward (of the trail toe, if one were to wish to assess the “forwardness”) at or immediately past impact, which in turn is the result of too-early downswing hip rotation. Why does all that matter when the ball is already gone? It matters because the club is only able to impart a fraction of the force intended for the ball, into it.
Simple high-school trigonometry tells us that if one plans to put “x” amount of force into the ball but moves the club off at an angle either inside the target line or above the ball, one ends up putting only a fraction of that force into the ball. Thus the “cosine factor”. When the club moves momentarily along the target line, the intended and delivered forces are both “x” (the force gets multiplied by the cosine of zero degrees, which is one). When the club moves off at an angle from straight down the target line, the intended force is multiplied a number between 0 and 1, thus resulting in a smaller quantity of force being delivered.
Golfers – professional and amateur alike – would do well to understand, based on THE COSINE FACTOR that the club must move along the target line momentarily past impact, and make swing changes accordingly, in order to maximize the force they are able to transfer to the ball from the club.
