Physics of the Serve
The game of racquetball
follows the basics tenets of physics. Here are the five physic laws that you must understand if you want a
photon drive serve:
Physic Law #1:
The lower the height of
the ball on the front wall, the faster the ball's velocity is needed to
get past the short line.
Physic Law #2: The higher the height of
the ball on the front wall, the slower the ball's velocity must be to
avoid a long serve and/or a setup in the middle of the court for your
opponent.
Physic Law #3: The angle of the ball's
approach equals the angle of the ball's exit. Most of the time, you want
to be in the intersection of this angle.
Physic Law #4:
For each inch of error on
the front wall, the angle of error in the backwall is magnified into
feet.
Physic Law #5:
The greater number of
walls that is involved in a serve, the smaller room for error. This
applies to Z-serves. The further you are away from the center, the
longer the serve and the wider the angle. If the angle is too sharp, it
will be a setup in the middle. If you want to hit a Z-serve with a low
degree of angle one side of the court, you got to hit it hard and high
for it to travel to the backwall.
