Why does tee fly backwards after teeoff?

Answer 1

When the club is hitting the ball, friction drives the tee forward in the hole, but it cannot escape the turf quite yet. After the club and ball have left the tee, the tee rebounds backwards in the widened hole, often freeing it to go backwards. This is usually a sign of a "clean" hit, but other results are also possible, such as a broken tee or one driven further into the ground.
