Re: Flight again (was Re: The Lizard of Oz)
I no longer play tennis, but did have a tennis scholarship when I was in
many years ago. If I remember correctly, the balls had fuzz so they
create enough drag to enable spin to affect the trajectory. In
takes about 5 games to wear the fuzz down to the point where the balls
floating long. In a five set match you'll usually go through two cans
and will end the match with balls that are starting to float again. In
hit a fast serve, you have to put considerable overspin on the ball to
down, particularly when going for the centerline. Again, after about 5
you have to start taking speed off the serve to get it into the court.
the sound of your question, I expect you already knew that.
