For our second project we made a physics video about sports. To first start we got a letter from Mr Pitti, our athletic director. Our objective was to inform our athletes how to preform better by using physics. I was grouped with Emmy Nam, Grace Guempel, and Maeille Weinstock. For project we chose to focus our video on the performance of running. To start the film making process, a film always has to have a script, so we started with that. When I thought that we were going to make a video about running, luckilly, we already had a runner in our group, Cate. The script took us about three days to complete and we were behind. So we planned a day where we would finish all of the videoing. When that day came we went to O'hair park t ofilm since Cate runs cross country. The videoing took approximately two hours to finish the filming of the runner. For the rest of the week we edited the video and finished the video by the due date.
Physics behind running
Many examples of physics can be found in running. What our group focused on in the project was velocity, impact force, projectile force, and acceleration. is not shown in our video, we calculated the projectile motion of the actual runner. By taking two vectors, horizontal velocity and vertical velocity, we were able to figure out the total velocity, which is projectile motion. For the horizontal velocity, we timed Cate running a distance and the found the quotient of the two numbers because velocity is equal to the distance over time. To calculate vertical velocity, we took the average distance her foot came off the ground and then divided that number over time. We also used this velocity to find the impact force and other measurements. The time is only average downfall time it takes for her foot to reach the ground from its peak. For the results of the two calculations, we used the Pythagorean Theorem, which is A squared plus B squared = C squared, to find the total velocity.
Impact force is when one piece of matter fits another piece of matter which creates the impact force. Impact force is equal to the amount of momentum. By getting those two pieces of information we set up an equation mv=Ft, or mass times velocity is equal to force times time. We found the mass, velocity, and force, then divided that by time. The answer was Cate pushing over 2000 newtons on the ground, therefor the ground was pushing 2000 newtons back on her.
Reflection
I enjoyed working on this project very much because I have leaned skills that I have not been able to get access to and been exposed to. What I took away the most from this project was realizing how much work filmmakers have to do to just make one scene. I think I did very well for not making any films before. Our group preformed very well with good time management, cooperation, and execution with our final video. Our group did not experience any problems with the making of the film. We were very composed and got our work done efficiently and on time. The things I think I could have done better was expressing my ideas more. I was very quiet throughout the project and staying inside myself. I also could have learned a little bit more about editing and computer work. Although the project was short I thought the time was well spent.
