Center of Gravity’s Effects for Golf Shots

The higher the trajectory of the shot will be for any given loft angle on the clubhead,the lower the center of gravity and the farther back the center of gravity is from the face of the club. Of the two CG locations that affect the height of the shot, the CG back from the face has a greater effect on the height of the shot than does the vertical CG (up from the sole).Nike SasQuatch Driver

The reason is that the closer the center of gravity is to the shaft, the lower the moment of inertia about the shaft axis will be, and the greater the tendency will be for the golfer to rotate the face of the club less open/more closed by the time the head gets to impact with the ball. The farther the CG from the shaft, the higher the MOI will be about the shaft axis, and the greater the tendency for the golfer to leave the face of the club open/less closed by the time the head gets to impact with the ball.

The closer the CG is to the shaft, the less tendency there will be for the golfer to push or fade the ball offline. The horizontal center of gravity location, or how far the CG is over from the center of the shaft, is a design factor that affects the accuracy of the shot. And the farther the center of gravity is from the shaft, the more tendency there will be for the golfer to push or fade the ball offline.
