Our Project
To create my physics of sports video: The Physics of Rolling, I worked with Brandon, Ethan, and Natalie. The basis for the physics of sports video project was to help the San Marin sports department's teams using physics to explain how to improve their performance. Lots of groups did videos of hitting and kicking balls, running, swimming, and more. My group featured rolling, a simple but helpful task that can protect you from a heavy impact that the ground might cause.
This project differed greatly from that of building the Rube Goldberg Machines. Instead of having a chaotic work space filled with loud noises of drills and hammers and the sounds of success and failure, there was a lot of time where you needed to figure out what needed to be done in what order. For example, my experience with the Rube Goldberg project was that the looming deadline made it harder to focus on the present (also your machine falling apart contributes to that), whereas in this project the deadline was set and we all knew what it was so we accomplished details as it needed to be completed. A lot of time had to be set aside for brainstorming and lots of good ideas just couldn't have been incorporated.
I can't say that I could choose a favorite between the two because both projects that we've completed by now had their advantages and disadvantages.
I feel like time management was much easier in this Physics of Sports Video. My group also could multitask and have people work outside of school and still get things done. We finished editing our video the day before we needed to have it uploaded, and that one day was filled with some anxiety. Perhaps if we had focused solely on our project during class time then we could have finished earlier and worked more efficiently. Also dividing up the work by having one person for each job would be good. Our group tried and for the most part succeeded in dividing up work, but I ended up feeling swamped some days when being told that the script I wrote prior wasn't to par, making me redo calculations and write a new script. I don't regret having taken those responsibilities but I'll use them to prepare for the future.

The Physics of Rolling
When you think about the physics of sports project, rolling isn't something that comes to mind immediately. You'd expect to see tasks in sports such as baseball and basketball and soccer, but rolling is a confusing subject for that. Rolling is a sport? Not necessarily. Some parkour professionals may beg to differ though. Rolling is utilized in every sport that could involve running. Rolling is a way to reduce injury when falling and keeping your velocity that you had before falling to continue whatever task it was to make you fall in the first place. Many soccer and football players fall occasionally and just sticking your arms out to cushion isn't safe and leads to injury and won't carry your momentum to help you recover and keep moving.
ConceptsForce: A push or pull. Weight is a force
Velocity: the speed of something in a given direction Acceleration: The increase in speed or velocity of something over a period of time Momentum: the quantity of motion of a moving object or body measured by a product of its velocity and mass |
How They Apply to RollingThe roller applies a force of 140 lbs (his weight) on the ground
The roller has a velocity of 3.375 meters per second (7.549 mph) while rolling. The roller also had a velocity of 3.08 meters/second while running before the roll and a velocity of 3.25 meters/second while running after the roll. The roll accelerates the roller by 0.895 meters/second every second. The momentum that you had before rolling is barely interrupted by the roll |
I really enjoyed working on this project. I had lots of fun with my group members. I thought that we all worked well together. We worked efficiently but also left room for some amusement within that work time. We rolled through this project with comfort and enjoyment.
