This paper describes a simple analytic model on oblique collision of a golf ball. In the golf, competition result is affected considerably by carry and trajectory of the golf ball. Therefore, the oblique collision has been reported both in experiments and numerical simulations in many people. Then, we need to study oblique collision behavior of a golf ball in numerical simulation by using simple model which is constituted by non-liner spring, non-liner damper and slider. In the results, the normal force during the collision is agreement but frictional force is different in the comparison of simple model results and FEM. The frictional force in simple model and FEM discussed.
