Physics Principles: Batting
History
People have generally agreed that softball was started from an indoor sport called baseball that was first played in Chicago 1887.
It soon became known by many names like mush ball, playground ball, kitten ball, diamond ball, and indoor-outdoor.
There were wide variances in the playing rules, dimensions of the field, and the size and type of playing equipment.
There was a rules committee that was appointed to publish and to circulate a standard set of rules in 1923.
That same committee was then later enlarged to form the International Joint Rules Committee which was on Softball, and which ended up including the representatives of a number of organizations that would promote and then it would sponsor softball.
The Amateur Softball Association of America was organized in 1993, which ended up coming to be recognized as the governing agency for the promotion and the control of the national competition.
In 1952 the International Federation of Softball was formed and acts as a liason between more than 40 of the softball organizations of many countries and their headquarters is in Oklahoma City, Oklahoma.
A women’s softball competition was added to the olympic games in 1996.
How the Game is Played
They play with 7 innings instead of nine innings.
base stealing is allowed but you must keep contact with the base until the ball has been pitched for the delivery to the batter.
The women have to pitch from 43 feet away from home plate.
The regulation field for softball is a diamond shape that's a little smaller than the baseball field and has an area of 60 feet.
The bats have to be round and can not be no more than 34 inches long and it also can't be more than 2.25 inches wide at the diameter of the largest part.
There is a popular type of pitch called slow-pitch that the pitcher is allowed to use.
Physics Principles: Pitching
Momentum of a Softball
Physics Principles
The rise ball is a key pitch for many softball pitchers.
The air pressure below the ball is higher which is the lifting effect for the rise ball.
The lifting trajectory of the softball keeps the ball from dropping as much as it would if it wasn't spinning.
A rise ball thrown with sufficient velocity might be able to rise higher than the original trajectory depending on the weight of the softball.
Depending on how fast the pitcher throws the softball the momentum will increase or decrease.
Since a 12" softball bat weighs more than a baseball the momentum of a softball would be higher than a baseball if both e going at the same speed.

Physics Principles
The laces on a softball create turbulence in the air.
Some air might remain longer than it should if the ball was smooth an the turbulence would drag.
When a pitchers throws a curve ball the drag is reduced on one side of the ball more than the other side causing it to bend to the side with less drag.
An example would be if a right handed pitcher threw a standard curve ball she would spin the ball so that the left side of the ball rotates towards her as the pitch travels to the plate.
The result would be in less air pressure on the ball's left side making it curve to the left side of the pitcher ile going to home plate which is going away from a right handed batter.

The pitch's velocity equals the force applied by the pitcher times the distance the ball travels before the release, in softball terms.
This is what explains why the softball pitchers use a long windmill windup.
The ball travels a greater distance by moving the ball in a circle than if the pitcher moved the softball straight back then straight ahead.
The ball accelerates until the leaves the pitchers hand which gravity and wind resistance start to reduce the softballs velocity, which is during a windmill windup.
In order to add force the pitcher would rock back a bit before she moves forward to complete the pitch.
To add the force is with all the forward motions she creates while pitching the softball.
Did you Know?
In softball you pitch differently than baseball. In softball you pitch underarm while you pith overarm or sidearm in baseball. Notice the difference from where each ball is at?
