For the physics of sports videos, each group chose a sport that they wanted to focus on. We then made a video that went into the physics behind perfecting that step. We had about seven class periods to work on our videos; this would include: filming, editing, recording voiceovers, and planning.
My group chose basketball as our sport, and the layup as the step we used in our video to show the physics of. Once we decided on the sport and the step, we started the storyboard and script right away. During our first two work days, we completed the storyboard. We were working on the script also, but we finished that on the third day. On the third day, we also finished our filming. Then something terrible happened...WE LOST THE SD CARD WITH OUR FOOTAGE!! We had to redo our filming the next day, because we didn't have a new SD card or camera to film with. My group still wanted to be productive, even though we didn't have the videos, so we had two of us record voiceovers, while the other two focused on the title page and music in our movie. This worked well, and we finished most of our voiceovers that day. The next work day we re-filmed our video and started to put everything together. We did not know how to use the program to make our movie, and could not figure it out, so we were very far behind. By now our voiceovers were done, but in the process of showing Mr. Williams, we realized that one of our times was way off, which made most of our other calculations way off. This meant that we now had another problem--all of our voiceovers were wrong. Sophia and I had to redo the voiceovers, but we finished this and made sure to check all of our work. When it was time to present to the class, my group and I were not at all ready; we barely had any audio, our music would cut in and out randomly, our footage was all in the wrong places, and it was way too long. Mr. Williams didn't even let the movie get to the end, it was that bad. Our group had two more days until it needed to be ready for the movie night premiere. The next day in class, my group really got to work. We figured out how to use the program with a little help from Mr. Williams, and we recorded new voiceovers--again-- but they were much shorter, we cut out the footage we didn't need, and put everything in the right spots. My group did not start out well, but our video is now presentable; everything isn't perfect, there are still a few things in the wrong spots, but we really came together to make sure it got finished.
Here is our finished video:
In our video, my group found:
Horizontal Velocity: the rate of distance covered horizontally (this velocity is constant)
Vertical Velocity: the rate of distance covered vertically (at an acceleration or deceleration of 9.8 m/s^2)
Total Velocity: the rate of distance covered in any direction (in a parabolic path when the object is thrown)
Force: the push or pull on an object
We found these concepts by using these equations:
Horizontal Velocity: the rate of distance covered horizontally (this velocity is constant)
Vertical Velocity: the rate of distance covered vertically (at an acceleration or deceleration of 9.8 m/s^2)
Total Velocity: the rate of distance covered in any direction (in a parabolic path when the object is thrown)
Force: the push or pull on an object
We found these concepts by using these equations:
- Horizontal Velocity - change in distance/change in time
- Vertical Velocity - acceleration due to gravity x time
- Total Velocity - vertical velocity^2 +horizontal velocity^2 = total velocity^2
- Force - force x time = mass x vertical velocity
