Evidence of Work
First we started by brainstorming ideas of sports that we could explain the physics of. We had many ideas such as physics of lacrosse, physics of round off back hand spring, and physics of a layup. The one that we decided to do was the physics of a layup. On the first day of filming we went up to the basketball courts and filmed multiple layups. On the second day we did the same thing and edited a small video. Our idea was to have multiple pro layups in the beginning with background music. We were also going to explain four physics, but we ended up explaining five. We had whole day to edit and film each other saying what physics we were going to do. We did it all and our project looked good.

Reflection
The project was fun and interesting. New group members and new project. Our filming and editing went quite well, but we made many mistakes while making the calculations so we need help from the teacher. While editing the movie a file got corrupted and we lost some film which dragged us backwards. We had to hurry and film new scenes on the last day but we made it. I may have made the calculations harder by slowing down and doing tricks while completing a layup. Next time I will think more carefully if it will effect our project. I think I still have to work on staying 100%. I will try and help my group out better next time. I got more experience at talking into a camera and I learned how to calculate certain physics of everyday sports. The bad part of our project was when our file was corrupted and we were sort of lost at first. The best part was looking at our final draft and realizing how good it was.
