PHYSICS OF SPORTS VIDEO
As our second STEM project we were tasked to create a video showing how San Marin's athletes can use physics to increase their sporting abilities. For our video we chose to take a closer look at the physics behind a soccer kick. The three main principals we focused on were velocity, force, and impulse vs momentum. The first step in creating our video was to write a script and storyboard what we wanted the video to look like. After this step was done we went out onto the soccer field and took data. By using a slow motion camera, we were able to find distances and times for our calculations. At this point, we started to edit together our video. The first thing we decided on was the music. This was a very important choice as it set the mood and tempo for the rest of the video. Next we started adding in video clips. As we chose new clips; voiceovers, transitions and overlays were all added in. The final touch was a quick credits roll and a message to the audience by Matt. After peer review, we added in a few new components and finalized the result.

PHYSICS CONCEPTS
Velocity - A vector quantity that describes how quickly an object changes its position
- We found the velocity of the soccer ball as it traveled through the air.
Horizontal - Will stay constant in a friction-less environment
Vertical - On Earth an object will be slowed at a constant acceleration downwards of 9.8 m/s²
Total - A velocity quantity that factors in both the horizontal and vertical velocities
Force - A "push" or "pull" interaction between two objects in which both objects are asserting a force upon the other
- We found the force exerted when the player's foot hit the ball
Impulse - A change in momentum, "How hard would it be to start this object moving"
- We found the impulse on the soccer ball
Momentum - A mass in motion, "How hard would it be to stop this moving object"
- Finding the impulse let us also find the momentum of the ball as it flies through the air
- We found the velocity of the soccer ball as it traveled through the air.

REFLECTION
Overall I think this project turned out very well. I do however think that a better result could have been achieved if our group had been able to all work in tandem throughout the project. For a large majority of the project I was working alone on our video. I recognize that this is in part because the design of this project does not favor collaboration. Video editing isn't something that is commonly done by multiple people but there are ways to incorporate multiple people into the process. However, when we needed everyone working the entire group focused and completed the tasks on hand. Our project could also had included more content. Our video was very minimal and only included the most important concepts. Even so, our final video was very well put together, as well as being fun to watch and easy to follow. This project is something we are all proud of creating as a team.
