Evidence of Work:
The past four weeks our class has been working on a sports video. A Physics of Sports Video is a video that deeply describes all the physics of a special action in a sport. For our video we chose to do the physics of a soccer free kick. We spent a few days on the calculations and most of them on making and editing the video. The first part of our project was doing the calculations. We calculated the force of impact, the total velocity, and many other things. We added some videos of professionals to show the audience what a free kick was. Our video included the calculations on a whiteboard to help the viewers understand how we got our answers. The hardest part of this video was editing or doing the calculations but it was still a really fun experience.

Force of Impact- The amount of force that is put into something when hitting another thing. To calculate it you need to take the mass and velocity and multiply that. After that you equal that to force times the time. We used this when Kaleb kicked the ball.
Momentum- Tendency of a moving object to keep moving (how hard it would be to stop). You would calculate this by multiplying the mass and the velocity. We used this when finding the force of impact.
Impulse- How long and how forcefully something is pushed. It is calculated by multiplying the force and the time. We used this when finding the force of impact of the foot against the ball.
Vertical Velocity- The speed of something going vertically. It is calculated by taking the acceleration due to gravity (9.8) and multiplying that by the time. We used this in finding the total velocity.
Horizontal Velocity- The speed of something going horizontally. To calculate this we divided the distance and the time. We also used this to find the total velocity.
Total Velocity- The final speed the object went, but it doesn't have to be up or down. We used the horizontal and vertical velocities to find this. We could use this to find the velocity that the ball traveled when kicked.
Reflection:
This project has been really fun and my group did really well. But I do have to work on a few small things for next time. I feel like I did well with working with my group on this project. For example, we all were nice to each other. When we were shooting the video I would always make sure that I was being nice to everyone. I also felt like I did well with the distribution of all the work. I did the first part of editing and then Wesley did the middle part and Kaleb did the last part of finishing touches. I feel like I could work on speaking up more because I had some ideas but I never said them or I didn't contribute to the conversation. We were talking about what the script should consist of and I didn’t really talk all that much during that discussion. Another thing I could work on is always being focused because some of the time I would mess around and not get stuff done. In conclusion, I am very happy the way my group and I worked together during this project.
