This study was focused on variation of ball"s trajectory depending on the attack angle and impact position on the clubface between clubhead and ball. At 115 mph(mile per hour) of an average clubhead speed, total distance, carry, ball speed, rpm of ball, top height and launch angle were compared according to the change of the attack angle (0°, 3°, 6°) and impact position (‘center’, ‘5 ㎜ up’, ‘5 ㎜ down’, ‘10 ㎜ up’), respectively. Total distance was increased with larger launch angle, and launch angle increased with larger attack angle. On the other hand, total distance was decreased with higher rpm, and rpm increased depending on the impact position in the order of ‘up’, ‘center’, ‘down’ due to the gear effect. Generally, total distance of ball was longer with increasing of ball speed, but this study showed that total distance of ball was longer even lower ball speed in condition of the ‘up’ impact position, because of lower rpm due to gear effect. But outside the normal impact range as like the impact position of ‘10 ㎜ up’, gear effect can not be fully expected. In other words, ‘10 ㎜ up’ impact position showed a gear effect resulting to lower rpm, but it showed lower ball speed due to outside the effective impact range. In result, the best for total distance of ball was under condition of an attack angle 6° and impact position at ‘5 ㎜ up’. On contrary, the minimum for total distance of ball was under condition of an attack angle 0° and impact position at ‘5 ㎜ down’ due to low launch angle, high rpm and ineffective delivery of clubhead energy to ball. Finally it have to be considered an attack angle, gear effect and effective delivery of clubhead energy to ball for the most total distance of ball.
