batting force
Physics of Topic

When you are swinging your arm around while you are pitching, you pick up momentum which increases the velocity of the ball.
The momentum that you acquire helps keep a constant speed and make the ball accelerate farther.
Your raw muscle strength is what creates momentum and it moves the ball at a faster motion.
Using momentum can take the stress off your joints and muscles.
Your arm is producing momentum but your body moving forwards increases the velocity.
pitching momentum
The normal force is being applied to the pitcher while the applied force is when the ball leaves the pitchers hands.
The normal force is being applied to the person batting.
The applied force is being used when the bat hits the ball.
This would be an example of Newton’s third law which states for every action there is an equal and opposite reaction.
Linear hitting is shifting the weight onto your back legs and then taking a small load of your hands so that you can launch forward.
Rotational motion centers around the hips.
You rotate your hips and turn your back foot like you are squishing a bug to help achieve a powerful and fast swing.
The catcher has to stop the applied force by the pitcher.
If that is not done the right way then catching the ball may cause pain.
The catcher has to try and distribute the force of the ball into their mitt but sometimes that force can be directly applied to their hand.
Inertia is constantly pushing the ball towards the catcher.
Physics of Topic
Sometimes when you make contact with the ball, the bat will vibrate.
The reason the bat vibrates is because it is losing energy and momentum while it is being swung.
When you are batting you want to hit the ball on the “sweet spot” of the bat which is located five to seven inches away from the bat.
History of Topic
The first softball game was invented in 1887.
A group of men at the Farragut Boat Club (gym) were listening to the football game played by Harvard and Yale.
A spare boxing glove was picked up by one of the men and was thrown at someone ready to hit it with a pole.
George Hancock, the inventor of softball, drew out a diamond with chalk so that it resembled a baseball field.
The gym was not as big as a baseball field so it had to be smaller.
To make the bat, he broke off part a broom handle.
After the first game Hancock came up with the rules.
As well as equipment...
A soft ball that was between 10 and 20 diameters
As well as a bat with a rubber tip which made it easier to play indoors.
For some time softball was played indoors as a winter league but as it got warmer, it was taken outdoors.
History of Topic
History of Topic
The fireman, Lewis Rober, had a big role in developing softball.
While his men waited for fire calls he needed something for them to do, so he made a field outside next to the station.
He made the game 7 innings so that it could be played in one hour while still letting the men be competitive and active.
History of Topic
The fall of 1933 was when the Amateur Softball association was made.
The association came up with standardized rules that were needed to play the game.
Softball became a sport for all ages which is why the association set rules for different age groups.
History of Topic
A 12 inch ball was used.
Depending on if it was slow pitch or fast pitch, the size of the fields varied.
The distance between each base was 55- 65 feet, and the distance of the rubber where the pitcher stands is between 35-50 feet.
Since 1933 the rules haven’t really changed there have just been more added.
Such as, how many players can be on the field, 10 for slow pitch and 9 for fast pitch, the mercy rule, stealing and sliding, batting orders, etc.
History of Topic
Fast pitch has become the most popular form of softball internationally.
Fast pitch pitchers can throw the ball the same speed as a major league baseball pitcher.
Women’s softball became an Olympic medal event in 1996.
The women’s US team won all 3 gold medals awarded for the sport.
Unfortunately softball was voted out of the Olympics by the 2012 games.
Interview questions and answers
1. Q: What experience do you have in softball/baseball? How many years played and coached?
A: Played baseball throughout high school. I coached my daughter’s softball teams for the past 6 years.
2. Q: Have you received any awards?
A: Named all-conference my senior year in baseball. Received a scholarship offer to play baseball for Bemidji State.
3. Q: What is your favorite memory of playing and coaching?
A: Enjoyed playing ball myself- but most of favorite memories involve watching Savannah and her friends play ball. It’s been satisfying knowing that I have helped many of them get a little bit better and hopefully enjoy themselves playing the game well.
4. Q: Words of advice for anybody new to softball
A: Enjoy the process

Interview Questions and Answers
5. Q: How does softball relate to physics?
A: Hitting the ball properly is almost entirely a function of physics. How far and hard you hit the ball is almost entirely related to the velocity of the bat, ball and plane of the bat through the strike zone.
6. Q: What are the proper mechanics for a good hit?
A: Hands inside the ball, weight transfer forward in a linear motion, follow through, high finish.
7. Q: What are the proper mechanics for throwing and catching a ball?
A: Throwing the ball is a function of getting maximum arm extension. Utilizing one; lower body and core properly allows for more power in the throw. Catching a ball is about aligning and moving one’s body effectively in front of the ball.

Interview Questions and Answers
8. Q: Have you met any famous players?
A: I know most of the Hudson Girls Softball team- does that count? I have met Barry Bonds, Jeff Bagwell and Kirby Puckett- all hall of fame players.
9. Q: Who did you look up to when you played?
A: My favorite player was Ryne Sandberg, second base men for the Chicago Cubs.
10. Q: What was/is the most fun part about playing and coaching?
A: working on a skill in practice and seeing it executed in a game.

Bats used in experiment
Aluminum bat
50% Composite bat
100% Composite bat
Scientific Method
1. State the problem
What type of bat will make the ball go furthest?
2. Make a hypothesis
We think the 100% composite bat will make the ball go the farthest and have the best hit
Scientific Method
3. Plan your experiment
Independent variable: the person we are experimenting
Dependent variable: the different types of bats being used
Aluminum bat, 50% composite bat, and 100% composite bat
A person batting and pitching
Large area
Scientific Method
Gather 3 different types of softball bats
Find someone who knows how to play softball and will be able to properly hit the softballs that are thrown at them
Go to an area with a large amount of space so you have enough room to hit and throw the ball
Scientific Method
Have someone pitch the ball to a person of your choice. Make sure they use the same bat for three trials
Record how far the ball went all three times
Repeat the last two steps 2 more times, but with different types of bats
Record the data
Analyze your data to see which type of bat made the ball go the furthest
Scientific Method
Scientific Method
Analyze Data:
The 100% composite bat made the ball go the furthest distance with an average of 61.5 meters.
When the batter used the aluminum bat, the ball did not go as far as it did with the two composite bats. Instead it went an average of 46.1 meters.
Scientific Method
Our hypothesis was correct. The 100% composite bat would produce the best hit which would then make the ball go the furthest. If we were to repeat this experiment we think it would show the same results.
How far the ball go also depends on who is batting and pitching. If we were to switch the people, the outcome may have been different.
interviewed Pat Kelley
Gather Data:
100% composite
The 50% composite bat was in between with an average of 54.9 meters.
Scientific Method
