While watching sports scenes you must have felt that your knowledge of physics is just not enough to understand all aspects of it. In this course you will learn which additional forces are at play in different sports and why a curve ball curves? or why a ping pong ball dunks? You will also understand the use of energy and power in basketball, cycling, and other sports. Science has been illuminating sports for decades and will play even more significant role in high-speed competitive sports of the future. This course will offer you a whole new way of viewing and understanding the sports you love. Group projects will help in exploring these topics further and at deeper level.
This is a short course which starts with the assumption that you know at least some basic mechanics. A few review sheets will be available and key concepts will be reviewed in the class too. By the end of the course, you will:
The real history of the subject is difficult to trace and the reader is referred to other texts. Here we would point out the 'modern history' of the subject. In early 1850s the subject of rotating artillery shells was explored by the German professor Heinrich Magnus. In this project he investigated sideways deflection of artillery shells which were rotating. In 1877 Lord Rayleigh wrote a paper on the irregular flight of a tennis-ball. It can be found here.

Starting with an introduction to basic concepts in physics learn why a curve ball curves, why a ping pong ball dunks, how the speed and temperature of bobsled critically define its trajectory and dynamics, etc. The course will try to build general understanding of physics needed to explain various sports in a greater depth and to appreciate the amount of science and engineering that goes into designing sporting equipment.
The following video will prepare you before coming to the class.

"Here is a link to "How Baseball Players See a Fastball" published by Barnet Dulaney Perkins Eye Center which details the science behind a baseball player being able to hit a fastball pitch. It highlights the amount of time it takes a fastball to travel to home plate vs. the amount of time it takes to blink and a player's ability to predict movement, demonstrating how truly amazing the hitting process is: https://www.goodeyes.com/bdp-news/how-baseball-players-see-fastball/.Here are some more links which may help students:

"I was searching for educational science websites and came across your page. We have created a free interactive guide to Kinetic and Potential Energy Our guide is easy to follow and contains numerous graphics that assist with the comprehension of the material."Contributed by Prof. Don R. Mueller on his work (Physics professor and former pro baseball pitcher)
"Concerning my work in tennis, which includes new ways to hit (serves and ground-strokes) and new racket innovations was covered briefly in the NY Times (2018) humorously in cartoon form: http://www.nytimes.com/2018/05/11/sports/tennis/don-mueller-rackets.htmlI wrote about my various racket designs (and functions) in this LinkedIn article: various racket designs (and functions)
News item from my Physics of Tennis event at the Wayne Racquet Club (NJ)
Finally, I show off a little ambidexterity in this next article along with my Two-racket Tennis friend from LaLa-land who was happy to have me include his photo in The Buffalo News. I do enjoy a rousing game of what I call Two-racket Tennis"
Some other Physics of Sports Courses and their Websites
Following links, taken from the website "Real World Physics Problems" are extremely useful:
Videos
These short video clips are for actual classroom presentation and can be used for activities and group discussions about a particular sport. They may also become the basis for a research project. Keep in mind that if you need to really study a topic, you will need to search for "high speed video of ..." to find good videos which you can analyze with a video analysis software.
General Websites
Physics of Computer Games
Online games
Experiments
Some publications of great value to this course:
Specialized Sports Papers
The objective of this section is to provide ideas on doing simple experiments using easily available hardware and software:
The following PhET and other simulations each has some relevant physics concept explained:
The following SimScale simulations have some relevant physics concept explained:
The timing of this course is such that it will end just before them as the 2018 Winter Olympics will begin on: Friday, February 9, and end on: Sunday, February 25. Hence you are encouraged to explore these sports during this course and then use your newly gained knowledge to understand different sports during Olympics.
You can also go back in time and see what happened in Sochi Winter Olympics 2014. There are 15 sports played during Winter Olympics. These can be snow-based, or ice-based. See What’s The Difference Between Ice And Snow?
Following sports are represented in Winter Olympics:
The next Summer Olympics will be held in Tokyo in 2020.
You can also go back in time and see what happened in Rio Summer Olympics 2016.
Following sports are represented in Summer Olympics:
If you have come to this page (or this part of the page) thinking that this is the CTY's (Center for Talented Youth) course of the same name, please understand that it is not.
However, I am the course mentor for that course too and hire instructioanl staff to teach that course. If you have worked with CTY in the past, or will be a TA/INST for this course in near future, you might already know me. The information here can be of value to you too as all these resources can be used there. You just have to understand that the audience is different and lectures here are not as interactive as they should be for young CTY students.
More information about CTY course can be found at the home Page for Physics of Sports offered by CTY
If you are looking for summer TA positions for this course at CTY, you may apply online and let me know via email address given below. The course is offered at UC Santa Cruz (Santa Cruz, California) and Roger Williams University (Bristol, Rhode Island) sites and CTY provides room and board on site. Travel to the site is NOT included.
