Physics of Sports Video

The Physics of Boxing!

Our task:

My group for this project was Erik and Stellan. Our goal for this project was to create a video that breaks down all of the physics in a sporting action and uses the physics concepts to show how to maximize performance in that sport. We chose boxing as our sport. Once we chose boxing, we had to create a storyboard and a script of our video. Both of them are shown below.

Original Plan (storyboard and script):

Physics of Sports Video

The Process:

After our storyboard and script were approved, we began filming. We started with the easy parts of our video which were the stance and a small clip of each punch being thrown. Then the next few days we broke it down and filmed each step of the three different punches. We also filmed the gloves used, some cool boxing warm-ups, and an actual clip of each punch being thrown in slow-mo. We decided to film most videos in slow motion so that the viewers could see each and every step and it would give us more time to talk about that punch.

After we were done filming, I worked on all of our calculations using each video we took, while my other group mates chose background music and found a real clip of a professional boxing knockout. Then it was time for us to do voice overs. We muted every clip we took, so behind each one we added our own words to explain what was happening and give the watcher some tips on how to do each step and how that would help.

Our Video:

My Movie 1.mp4

And finally, it was time to piece together our video and create our finished product. We used iMovie to edit it all and we put every clip in the order we wished to have it in. We were able to add music to it, cool transitions, and our voice overs too. This whole process took about 2 weeks and it was very stressful but fun at the same time.

Calculations:

The Jab:

Horizontal Velocity:

  • the horizontal velocity was 3.6 m/s since we found that the horizontal distance (0.8m) divided by the time (0.22s) resulted in 3.6 m/s

Vertical Velocity:

  • the vertical velocity for the jab punch was 0 m/s because there was no vertical distance for this punch since it is supposed to be all horizontal

Total Velocity:

  • the total velocity was 3.6 m/s since there was no vertical velocity which means it was all horizontal velocity for the jab punch

Force of Impact:

  • the force of impact on the jab punch was 216 N or 48.5 lbs...

The Uppercut:

Horizontal Velocity:

  • the horizontal velocity was 3.1 m/s since we found that the horizontal distance (0.64m) divided by the time (0.21s) resulted in 3.1 m/s

Vertical Velocity:

  • the vertical velocity for the uppercut punch was 4.25 m/s since the vertical distance (0.85m) over the time (0.2s) gave us 4.25 m/s

Total Velocity:

  • the total velocity was 5.26 m/s since the Pythagorean theorem states that 3.1^2 + 4.25^2 = c^2 which would result in 5.26 m/s

Force of Impact:

  • the force of impact on the uppercut punch was 315.6 N or 71 lbs...

The Hook:

Horizontal Velocity:

  • the horizontal velocity was 7 m/s since we found that the horizontal distance (0.44m) divided by the time (0.06s) resulted in 7 m/s

Vertical Velocity:

  • the vertical velocity for the hook punch was 1.8 m/s since the vertical distance (0.82m) divided by the time (0.45s) equaled 1.8 m/s

Total Velocity:

  • the total velocity was 7.2 m/s since the Pythagorean theorem states that 7^2 + 1.8^2 = c^2 which would result in 7.2 m/s

Force of Impact:

  • the force of impact on the hook punch was 432 N or 97 lbs...

Reflection:

This project went through many phases and turns. At the start it was really fun and my group got along really well. And then as time passed, our feelings towards each other and the project changed. I think we began stressing too much about not finishing that we lost confidence in one another and didn't listen to anyone but ourselves. The sudden week off of school didn't help either because we found ourselves in a crunch for time. I think one thing I can definitely work on for our next project is my time management skills. This falls under the conscientious learning category since I need to become more aware of everything going on around me. Another piece I can improve on is my collaboration. I need to learn how to work better as a team and not be so demanding and bossy. I can do this by not getting letting things frustrate me so easily so that I won't get mad at my teammates when I happen to be in this mood and I can also learn to have more fun when doing projects like these because that will make me happy and positive while we work.

During this project, I think I did pretty well in a few of the 6 C's categories. I excelled in the communication part of this project since my group and I would never stop talking. We were able to start off strong because we communicated and shared all of our own ideas and thoughts toward the video. Another piece that went really for me was my critical thinking. Last project I wasn't necessarily the "leader," so I didn't use my thinking skills as much as I had to in this project. Since we lost time to work on our project as a group, I think that is when my critical thinking skills really showed up. I needed to do all of the calculations and video editing on my own because we weren't able to do it together. The missed days of school have helped me in this category by making me think critically about everything now.
