Physics of Sports Video
For this project, my group did a video on the physics of a volleyball serve. I worked with Casey Elmhirst, Beau McAndrew, and Taylor Rich. I play volleyball, so it was easy for us to get footage from games and warm ups. We also filmed some serving on the tennis and basketball courts. We had some time management issues, but we were able to finish on time. The project was also harder because Taylor hurt his back and was only there for the first two days and the last day. However, we managed to get most of the filming and calculations done without him, and I think our video turned out pretty good.
Concepts
One thing we calculated in the video was the force on the ball. We did this by using the equation mv=Ft (mass x velocity = force x time). We found that the mass of the ball was 0.27 kilograms, the velocity was 15.65 m/s, and my hand was touching the ball for 1/120 of a second. We then solved for F and got 507 newtons, which is about 114 pounds.
The other thing we calculated was vertical and horizontal velocity. We did this by using the formula
v=Δd/Δt (velocity = change in distance divided by change in time). The horizontal velocity was 15.65 m/s, and the vertical velocity was 2.94 m/s.
Reflection
Peaks- One thing that went well during the project was our team collaboration. We always agreed on what to do once we picked a sport, and we worked together and apart very well. For example, Beau and I would go film while Casey worked on the script for the voice-overs. Another thing that went well was our editing. I have experience with Windows Movie Maker, so we didn't have to figure things out as we went along. We also had extra videos and pictures, so we could just substitute another one in if the original one didn't work.
Pits- One thing we struggled with was time management. For the first two days, we didn't really get much done.We were trying to do a storyboard app, and we ended up messing around with it instead of working on planning our video. However, once we switched to using paper for the storyboard, things went a lot faster. We were also divided on whether or not to do football or volleyball for a long time. Another thing that did not go smoothly was recording our voice-overs. There was a weird glitch where it would record as soon as I had clicked voice-over before I even clicked the start button, but we solved that by clicking the start button instantly instead of waiting a few seconds. The program also deleted some of the audio files, and we had to go out into the hallway right before we were scheduled to present and re-record them.
One thing I learned about myself is that if I know how to do something and the rest of my group doesn't, I tend to hog all of the work. I need to work on letting other people have a chance to do things as well.
A skill I learned was how to do certain things in Windows Movie Maker that I couldn't do before, such as change the speed of video clips and add music.
