Calculations are presented on the trajectory of a golf ball that rolls across the inclined surface of a golf green. The ball follows a curved path and comes to a stop at a point displaced at an angle to the initial launch direction. It is shown that the displaced angle is independent of the launch speed but depends on the launch angle and the ratio of the incline angle to the coefficient of rolling friction. The stopping distance is proportional to the launch speed squared. A simple experiment is described to check the calculations.

高尔夫球在倾斜果岭上的轨迹

对高尔夫球在高尔夫球果岭倾斜表面上滚动的轨迹进行了计算。球沿着一条弯曲的路径运动，并在与初始发射方向成一定角度的点处停止。结果表明，位移角与发射速度无关，但取决于发射角以及倾斜角与滚动摩擦系数的比值。停止距离与发射速度的平方成正比。描述了一个简单的实验来检查计算结果。
