The stiffening members are all located within 1 inch from a rear surface of the face section measured along a plane normal to the center of the face, and are spaced by a distance of 0.500 to 2.00 inches within the hollow interior.SELECTED DRAWING: Figure 1ジェームズ エー. セルガ...
Other things learned, confirmed, or suspected were that ball bounce is variable even under identical impact parameters, energy return increases if impacts are preformed on the same axis, balls never truly regain their original shape, shape influences bounce speed, and percent energy return is indepen...
So say that optimal speed sits at about 36ish mph .. that impliesone(of many possibilities) set of inputs to get that 36 mph solution is an approx 30 mph swing speed with a 1.2 smash factor. One takeaway I see here is the best %tge wedge shot for distance control is one where y...

move the clubhead through the impact zone, the higher the resulting ball speed will be. As clubhead speed increases, so will the ball speed -- all else being equal -- which should result in more distance. In many cases, "golf swing speed" and "clubhead speed" are used interchangeably....
But it is evident from Figure 1 that even small changes in CL affect both speed and distance more than changing CD. Figure 2 shows how drag, lift and gravitational forces combine to determine the shape of a trajectory. Figure 2 — Forces acting on a tennis ball in flight: (a)Drag,...
The warm-up was divided into two parts: the first part consisted of a 5 min activation on a cycle-ergometer at a self-selected speed, followed by 5 min of dynamic stretches involving arms, legs and trunk, akin to a pre-match basketball warm-up. In the first session, prior to the ...

Drag vs Speed The upshot of all of this is that a slow-moving football experiences a relatively high retarding force. But if you can hit the ball fast enough so that the airflow over it is turbulent, the ball experiences a small retarding force (see right). A fast-moving football is ...
