The Physics of a Homerun⚾️
This project was to improve our understanding of and performance in sports by applying physics. For our physics of a sports video we decided to do the physics of a home run. We did this because we all agreed that it is the most interesting subject to research and because one of my group members plays baseball. After we research the topic, we decided what frames we wanted in each video and what we were going to say in them. Once we figured out the layout of the film, I calculated the physics behind the swing of a home run, then we found and recorded our friend hitting a home run for our physics of a home run video. From there our group, recorded voice overs and synced them on to the videos . Then, I edited the videos, adding music and some captions to finish off the film, and then added it to Youtube.
Physics and Calculations
Velocity: the rate of covered distance in a direction. It's units in measure are usually meters per second or miles per hour. For our video we found the ball coming in from the pitch and off the pitch (see below), to put it into equation v =distance over time to find the velocities which were 23.39m/s and 14.31 m/s.
Vertical velocity :the rate of covered distance upward. It's units are usually meters per second or miles per hour. We found the vertical velocity by using the equation V=acceleration due to gravity times by time in air divided by two. The vertical velocity after putting the numbers in was 20.874 m/s.
Horizontal velocity: the rate of covered distance horizontal. It's units in measure are usually meters per second or miles per hour. We found the horizontal velocity by using the equation V= distance divided time. After putting all the numbers In the vertical velocity is about 14.31m/s.
Force: the push or pull on a object because of change in motion. It's units in measure are N, and for our video we calculated it in the equation force times time of ball on bat = mass of ball times velocity of ball. After putting all the calculations in except the F in the equation, you get the force of 8,015.82N.
Mass: Amount of matter in an object. It is measured usually in kilograms and pounds. We found the mass by putting it on a weighing scale. In our film the mass is 5.25g or 0.148835kg.
Time: a progress of events. It is calculates usually by seconds and hours. We used this in many of our other equations to solve for them. To find we went frame by frame on our video to get how long the ball was in the air, which was 4.26 s.
Distance: the amount of space between two points. It is usually calculated in meters and miles. We used it in many other equations, to also solve for them. We found this by using a measuring stick, from the starting point to the ending point.

Reflections
During this project we had many ups and downs. Some of the things that went poorly were not having everyone contributing into the project evenly. Sometimes one person would be working on the calculations or scripting while another group member would be messing around on the computer. Also filming the vidoes could have gone better. We had to spend more than two days getting a video of a home run from fellow students because we shot our first home run video the wrong way. There were some things that went well in making this film. We covered all our steps, calculations, and we made it somewhat enjoyable to watch. For example, we added a funny video of someone falling over when swinging to show what not to do. I also added captions to the video to show how the calculations worked.
During this video I learned new skills, and something new about myself. The skill I acquired from this video was the ability to create and edit a video. Before I didn't know what to even go on to create one, but now I know how to add in videos, crop videos, add voiceovers, and add music. What I learned about myself in this video is how to take the initiative when no one else did. When people in my group were messing around I worked extra hard on focusing and doing the work we had to complete, like the calculations and the script. There are many things I can improve on in this project. I should have made sure my team mates were more on task when I asked them to be. Next time I will continue to persist them about doing their work instead of just leaving them alone, and thinking they will do it. Another thing I will work on is my attitude and demeanor. Sometimes I would get frustrated with them and I would let it show, which was not ok. In the future I will keep that frustration to myself and try to keep a more positive attitude, towards the project and my teammates. In all though, it was an ok project.
