Directional relationships of the golf ball with lie and loft angle of the putter

퍼터의 라이각과 로프트각이 퍼팅한 공의 방향성에 미치는 영향

Less than 1 % directional error in the range of 5 meters in the green could cause a stroke or more. Although there are several reasons offsetting the direction of the golf ball, lie angle and sidespin effect are the most crucial factors of the putting game. Simple equation is conformed to the experimental results of the deviation of the directional error in all distance. Also, the experimental results of the putting robot show that there are significant side spin effects.
