The
Physics
of
Pitching
Pitching
in
Softball -
this is an underarm
motion, making one full rotation of the arm, called
the "windmill", and releasing
the ball at the hip
with a snap of the
wrist.
In softball, there are basically four basic types of
pitches that I
learned.
Fast Ball - the most
common pitch, the ball is thrown straight into the strike zone
at a
high velocity, the arm
motion
is the same as the one described in
Pitching a Softball.
Drop
Ball - in this pitch,
the
pitcher
snaps
their wrist a little earlier, before the hand passes
the hip. This motion puts more top spin on the ball which
Rise
Ball - to get
a good
rise ball the pitcher needs a low release, and a specific hand movement
where they have to "Turn the door handle" or curling your fingers into
your palm at the release.
Change
Up
- this pitch is
a slow version of the fast ball, to achieve this, the pitcher must
release the ball with the palm down. You let the momentum rip the
ball from your hand.
Rise Ball
The momentum of the "windmill" motion plus the
momentum of
your
body moving forward increases velocity. Also, the release of the
ball can change the spinning and curving of the ball.
Wrist
positioning and movement can change
the angle of approach, and the
rotational axis of the softball.
Pitchers use the seams on
the ball to alter the spin
on the ball which
changes the direction.
The faster the ball is pitched, the faster the ball will travel
after
it is hit.
This is how the speed of a pitch can change the arc of the pitch
