Overview
In this project our class is doing the physics of sports. My group and I are doing the physics of darts. Before we even started making the video we had to make an outline and a script. We chose darts because it is an unique game that most people do not recognize as a sport. To make our video we used a video making program called iMovie. In the first part of our video we have the intro of our video with me and my other two group members. After our intro my group member explains the back round information of darts. Then my whole group and I explains the important aspects of throwing darts. Then one other group member and me explain the physics of one of us throwing the darts. After that my other two group members explain the physics of a professional dart thrower. Then my group members uses pictures of me to demonstrate where your body should bee positioned. Then we compared the force of a dart to lifting up a baby. Then thats the end of the video.
The Math Behind the Sport
When we were finding the physics behind dart throwing we had to use some specific techniques. Since when timing the dart throw there is a chance of human error we used slow-motion cameras. We found the frames per second then calculated the time. Here are our calculations and the formulas we used in our video.
Student Dart Throw
Vertical Velocity is: v vert = ag*t. Vertical Velocity: 2.254m/s
Horizontal Velocity: v horiz = d horiz/t Horizontal Velocity: 9.5m/s
Total Velocity: Use pythagorean theorem put in Vertical velocity in for b and Horizontal velocity in for a. Total Velocity: 9.76m/s
Acceleration: v/t Acceleration: 69.71m/s^2
Force: F=ma. Force: 1.36Newtons

Reflection
When I looked back on the first day we started this project I was excited to work in a new group and work on my leadership goals during this project. During the project my team got along pretty well until the end. We were always laughing and making jokes and at the same time still pretty productive. Also when we started shooting video with the dart board was fun because we got too mess around a bit on how to make the goofiest throw and other fun things. But then there were the not so good things. When I was doing the calculations for my group members throw I miscounted the frames but buy the time my group and I realized it was incorrect I had already calculated all the way through force. Then I had to redo the calculations for my group member's throw. Another difficulty that we encountered during our project was that our group got off task but more specifically it was one person in our group that was off task. But in the end it did not really matter because we finished our video and I think its pretty good. What I did in the project was several voice overs and the calculations for my group member's throw.
