The purpose of this study was to investigate the results of putting stroke which are face angle at impact, swing path of club, and green slope. For this study, a pendulum putting machine and a movable plate were used. Ball rolling distance was set at 1.2m. The control group(CG) does not have an angle and for example, the face angle is 0 degree, the swing path is 0 degree and the green slope is 0 degree. Nine experimental groups have one other condition. The origin of the coordinate was set at the corner of the plate and the ball was set on(70,0). In this study, x stands for direction, y stands for distance, and x+y unites a distance and a direction. Results suggested that the slope of the green was exposed to affect the big effect on the direction of move of the ball the most. The face angle has an effect on the direction of the ball in case one is big(more than 2 degrees). However, small angle did not change the direction of ball movement. The distance of the ball is almost constant(less than ±5cm) in spite of the transformation of the club. In the case of a distance and a direction, the slop of the green affected the big effect most. The face angle of 3 degrees affected big effect.
