Our second project of the year is the Physics of Sports Video. My group did the back handspring. It was very engrossing to know how to do one and know what to do and what not to do. Also, to know the physics was really enjoyable and good to know. The calculations we did took a bit of time but in the end they helped a lot. The first couple days we worked on this project we did scripting and story boarding. Scripting is what we were going to say and story boarding is the pictures and the clips in order. The next three days or so we did filming. The last five days we did editing and more filming. We edited and edited and edited because our group wanted to make changes or we needed to.
Physics Concepts
Force- a push/pull on an object. We used this in our project to calculate the amount of force the ground would exert on Kendal's legs and arms. The force she exerted was 394.09 N.
Momentum- tendency for moving objects to stay moving. We calculated this by taking the mass of Kendal's arms, 5.17 kilograms, and the velocity, 7.7 m/s, and multiplying them to get the momentum of 39.809 Ns.
Velocity- rate at which an object goes a certain distance. We got the velocity of her arms by dividing the distance which was 6.6 m and the time which was 0.86 seconds and finally got the velocity of 7.7 m/s.
Work- amount of energy put into something. We used this to find the energy a person put into the back handspring if they did or did not arc their back. Work is force times distance and the work is 483.745 J.
Impulse- how long or forcefully a person exerts on something. We used mv=Ft to find impulse which is mass times velocity equals force times time.
Newton's Third Law- every action has a positive and negative reaction. We used this to find how much force was exerted from the ground to Kendal.

Reflection
This project was an amazing experience. I enjoyed my group a lot. They were very wise and taught me a couple things. They made sense on everything we went over. In the end, we were all happy and enjoying working on the project. The scripting and storyboarding went great. We got it done pretty quickly so we could work on filming. The filming on the other hand didn't go so well. We had difficulties doing the back handspring on a mat or on the ground because of bad schedules and forgetting things and stuff like that. I learned many things about myself during this project. First, I learned a lot about physics and how things work. I learned how the physics of a back handspring could actually help you do a back handspring more efficiently. Second, I learned that I am good emotional support. Opposed to when I was working, I was also trying to lighten up and cheer up the group. I was popping jokes and just being funny and kind hearted which kind of helped us work better. Also, it made us better friends. Two things that could have gone better was my work ethic and productivity and my computer skills or technical skills. My work ethic and productivity was pretty good but sometimes I just had to sit back and listen to my group and pop in when I had an idea. My technical skills are very bad. I am not so good with computers but I also learned some things about it. My favorite part was when we were out on the field filming. We were trying to get the what not to do's for the video. It was very fun because we were all laughing and having a good time. It was hilarious to watch me and Aditya's fails back on video and reflect on them. Our lowest moment is when we didn't know what to do. We had a time where we had no idea what to do and were just sitting down doing nothing. That was very brief though and after a little bit we started to do more. This project sparked something in me and I can't wait to do something like it again.
