The Physics of Penalty Kicks Video
Our Project
Soccer is a fascinating sport to think about in terms of physics. The round ball can be hit from many different angles and with varying amounts of surface to surface contact (point of shoe for minimum contact; laces for maximum contact), and with different methods of force creation from the body. For our project we focused on one main and diverse area of soccer the penalty kick.We had a few weeks to explore the physics behind our chosen project and learn what ever we could. Then make a video that shares all of our new found knowledge with the world and help people build on there ability to do the action.
The Physics
Potential Energy : The form of potential energy we were looking at during the project was primarily potential energy due to gravity.
Vectors :They are magnitudes that include a direction . We used trigonometry to combine vectors together to find the total velocity of the ball at several points during the flight. Vectors have no specific units, because it is not a concept.
Kinetic Energy : . Kinetic energy is mostly transferred from one object to another.

A Penalty Kick
A penalty kick can be one of the most efficient and persistent way of scoring but it isn't as basic and easy as it seems. It consist of three main steps: the run up ,the contact and the follow through. The run up is all about velocity its what starts the whole movement. The contact is about force and starts the actually movement of the ball, in our case the contact was about 80 lbs of force on the ball which weighed 15 oz . Finally the follow through which is determining factor for whether the ball flies with power of not.
How to Improve your Penalty Kick
When you slow down while taking the run up for you kick it slows down and lessened the forward velocity . So instead of slowing down you speed up it will give more forward velocity giving your kick maximum power . If you combine this with the other fundamentals we talked about in our video above you can perfect your penalty kick to an extreme amount.
Reflection
After doing this project i can never see my favorite sport soccer the same , but in a good way. For instance when i am playing its almost as if i feel the step by step physics of every action i do. This project has also improved my soccer skill greatly.
Over all this was one of my favorite projects that i have ever done. From the topic to my team mates i felt the whole project was a over all success and i would loved to do more things like this in the future.
