[time-nuts] OT: Not pendulums or atomic clocks or gravity

You don't get hit in the face because there is a phantom
force that attracts the ball towards the hole, but only after
it has been hit.

Or maybe it's the spin . . .

Since you have all enjoyed this discussion on rotating non-inertial
frames of reference so much, here's another one for you.

In golf, a typical pitching wedge has an angle of 45 degrees. Since
angle of incidence equals angle of reflection why doesn't the ball
bounce off the club, go straight up and hit you in the face? (A good
golfer would hit it 100m.)
