Finding the Perfect Penalty Kick
Overview
The goal of this project was to find a sports technique that is more succesful than the current technique. Our team choose to find the physics behind soccer and find the perfect way to take a penalty kick. We then created a video to show how to complete this technique.
Concepts
Momentum:
Momentum is how much an object wants to keep going. To have momentum, an object must be moving. In this video, we found the momentum of the soccer ball, in flight, by using the equation P=mv or momentum is equal to the product of the object's mass and the object's velocity.
Impulse:
Impulse is the amount of shove placed on an object. It is similar to force in that it is also has a direction involved. We used the impulse of the ball using the formula, J=ft or impulse equals force multiplied by time. Impulse and momentum will always be equal for an object.
mv=ft:
The equation, mv=ft, was vital for checking our data. Because Impact and momentum are equal values, we can combine their two formulas. We would change P in P=ma to J which can then be changed to ft because these are all equal values. This cross checks how accurate our information was and allows us to make sure we get correct results.
Vectors:
Vectors are different amounts of magnitude in a direction. They can be shown with arrows. Vectors are usually associated with force or distance in physics. In this video, we used the pythagorean theorem to find the distance from the foot to the goal.

Reflection
This project was very successful. Our group handled the timing of this very well, we organized the filming, recording, and editing in a flexible manner where we could easily change it. This was beneficial to out final product, because we had more time for editing and making sure our best work was included in this. Another peak of mine was collaboration. I really feel I have improved in collaborating with my group and making sure every member has a job that they can do. In my last group, collaboration was one of my weak areas with communicating to every member of the group. I could still improve on some things as well. One example is my speaking in the video. Next time, I will make sure that I am really enunciating my words and making it easy for the viewer to understand. Another improvement I could make is prioritizing. There were a few times during this project where I was focussing on elements of the video that were not as important as others. For example, instead of working on the calculations, I searched for music for the video which is much less important than calculations. Next time I will make sure I focus on the fundamentals first before going on to other elements.
