But for the higher-handicap player, the goal must be for the club head to pass as nearly as possible back through the position the club had at the beginning of the backswing, the so-called address position. It is worth noting that by the time the first vibrations travelling up the shaft have reached the hands, the ball is taking flight. 0004 Putt Chip Pitch Approach Drive Figure 3A Contact times between club and ball. transmission of the impact. So as the saying goes—just hit it—nothing more can be done.

19 N. 44 N. 7 times the ball weight. 19. 6 oz. 5 oz. and the drag 3 or 4 oz. It seems likely that these were estimated from the Davies (1949) data, whose lift coefficient for this case is in approximate agreement with Smits and Smith (1994), but drag coefficients are about one-third too high (Bearman and Harvey 1976). 2 rad/s). 29. From Eq. 77 N. Almost two decades after the Bearman and Harvey study, the R&A/USGA sponsored further wind-tunnel investigations, which were published by Smits and Smith (1994) in the World Scientific Congress of Golf (WSCG) II.

0 degrees. 0 degrees. For the latter, it would produce a large slice if the face was 3 degrees open to the club path, or a large hook if it was closed. The multiplier 57, approximately equal to 180 divided by pi, comes from conversion of the scientific radian measure of angle to degrees. These calculations raise a very important point. With a low-lofted driver, quite amazing precision is needed to keep the ball in the fairway. In this regard, most amateur players use drivers with far too little loft, resulting in too much difficulty with direction control.
