UNDERSTANDING COG: Center of Gravity Placement
Center of Gravity (CG or CoG) is the point at which all of the weight of an object appears to be concentrated. An object can be balanced on a small flat point placed directly beneath its center of gravity. That may sound complicated, but itreally comes down to balance. Have you ever balanced anything on the tip of your finger, or as the R&D guys occasionally do, the tip of a pen? The physical point at which an object is perfectly balanced…where it doesn’t tip over one way or another and crash to the floor, that’s its center of gravity. As you might expect given its label, the center of gravity is always located very near the center of the clubhead.
WHY CG LOCATION MATTERS: CG IS THE SINGLE BIGGEST INFLUENCER OF HOW YOUR DRIVER PERFORMS.
CG location matters because it heavily influences both performance and feel. How high your driver launches, how low it spins, how it feels, and how it sounds at impact, that all begins with its center of gravity. Despite having CG locations that are only millimeters apart, a Ping G30 plays very differently from a Callaway Big Bertha Alpha Double Black Diamond. Why? CG location. For those clubs with movable weight (adjustable CG technology), moving those weights around can alter performance significantly. Changing the CG location changes performance.
