Abstract

In this paper, the golf club head hit the golf ball moves at a constant velocity, then move in the same direction at a constant velocity of the golf club head, the velocity of the golf ball was hitting and flying the golf ball is calculated. If velocity is different before you hit the golf ball, each of the velocity of the golf ball is calculated. The purpose of this paper is to make it easy to find out the velocity of a club's head, the mass of a golf ball, the velocity or the direction of a golf ball after impact in playing golf. The results of the experiment are represented in tables and figures. And we also propose the comparison analysis between our research and other traditional ones, the implications, and futhur studies in the future. The results of this study, unlike other studies, it was can be seen that measurements of several factors superior to the measurement of the velocity of the golf ball.

본 논문에서는 골프채 헤드가 골프공을 일정속도로 움직여 치고 난 후 골프채의 헤드는 같은 방향으로 일정 속도로 움직일 때 골프공을 치고 날아가는 골프공의 속도를 구한다. 골프공을 치기 전의 속도가 각각 다를 경우의 골프공의 속도를 각각 구한다. 골프를 칠 때 헤드의 속도, 골프공의 질량, 임팩트, 임팩트후의 날아가는 속도, 그리고 임팩트 후의 이동 방향 등을 쉽게 알아보도록 하는 것이 본 논문의 목적이다. 실험 결과는 표와 그림으로 자세히 나타나 있고 본 연구와 기존 연구와의 비교 평가 결과와 시사점 및 향후 연구 방향도 제시하였다. 본 연구 결과는 다른 연구와 달리 몇 가지 요소들의 측정으로 우수하게 골프공의 속도를 측정함을 알 수 있다.
