For this unit, we made a video on the physics of a lacrosse pass, shown above. The first thing we had to do was make a script and storyboard, which took two days. We spent one day taking all our film, and pulled the rest from Youtube. We spent another day getting all of our voiceovers, then spent two days editing. After that, we showed our unfinished video to the class, and got some pointers from Mr. Williams. We spent one more day on editing, and then we were finished.
Concepts Used:
Impulse: Represented by J, impulse is how long and hard you push something. It is measured in Joules, and it's equation is J=Ft
Momentum: Seen in equations as a p, momentum tells you how hard an object is to stop. It's equation is p=mv, and it's unit is Joules
Force Of Impact: This concept states that momentum and impulse are equal, or that p=J. This also means that mv=Ft. This is useful because if you have mass, velocity, and time you can find force.
V(vertical): Vertical velocity is how fast an object is moving up or down. It is calculated using V(vertical)=at. It is measured in meters per second.
V(horizontal): Horizontal velocity is how fast an object is moving horizontally. It is measured using meters per second, and is calculated by dividing D(horizontal) by time.
V(total): Total velocity is how fast an object is moving in a 3d plane. It is measured in meters per second, and is found by making a vector diagram of Vvertical and Vhorizontal.

Reflections:
One thing I did well in this project was the numbers. I actually enjoy math (sometimes), and I had fun learning new things. If I had any problems, I asked Mr. Williams about it. I also found out that I do some of my best work behind the screen. I didn't have a prominent role in our video, but I did half the scripts and all of the calculations, so I feel good about it. One thing I didn't do well was stay focused near the end. I tried, but editing the video was at most a two man job, and I wasn't one of the two. I helped with the onscreen calculations, but that was mostly it. A thing I could do better would be to take a more active role. I feel that some of my ideas were overlooked because I wasn't loud or insistent enough, and I don't want that to happen again.
