Overview
During the month of October, my STEM group and I worked on the Physics of Sports Video project. The goal of this project would be to choose a sports action and to analyze it and find ways to improve the action. During the first week of the project, we brainstormed what our sports action would be and made somewhat of a story board for our video. We concluded that our action would be an aerial (a gymnastics technique which involves a sideways cartwheel-flip). We started off by getting footage of Lindsey performing the aerial. We then took calculations and started to edit our video. Next, we did the dialogue of our video, in which we recorded our voices on the laptop, and edited them over parts of our video. We then finished our video and presented it to the class.
Reflection
I had a blast analyzing and taking calculations on our sports action. This was definitely an enjoyable project, and I learned a lot in the process. One of my favorite parts of the entire project was getting to edit and create the video. I learned many skills including adding in dialogue, trimming videos, and lastly, how to make a video presentation on a laptop. I also enjoyed the hands on work in this project. Most of the time we were outside and gathering data, instead of being inside and editing. My group also got along extremely well, and we had little-to no conflicts within us. We were definitely a solid group and we accomplished a lot during the project. however, we got off task a few times and we were easily distracted and would talk with other groups.
One of my favorite parts of the entire project was being able to see the other groups video presentations. I felt like I learned a lot by just watching a few groups present, but it was also pretty cool to watch them break down their sports actions. This was one of my favorite projects of the year and I really enjoyed getting to work with the people in my group.

Concepts
- To find the velocity of the aerial, we measured the total distance traveled in meters and divided that by the time it took to complete the action(V=d/t): V=8.18m/2.56s=3.20m/s
- We found the momentum by finding Lindsey's mass in kilograms(kg) and multiplying that by the velocity(M=mv): M=54.3kg(3.20m/s)=173.76kgm/s
- The force exerted on the ground was found by measuring the time her foot was on the ground when she landed and using the velocity, and dividing both sides by the time(Ft=mv): F(0.1s)=173.76/0.1s=1738 Newtons
- To find the force that pulls Lindsey down at the top of the aerial, we multiplied the momentum by the acceleration due to gravity(F=ma): F=54.3kg(9.8m/s^2)=532.14 N
- The potential energy at the top of the aerial was found by multiplying her mass by the acceleration due to gravity by the height she reached while in the air(PE=mgh): PE=54.3kg(9.8m/s^2)(0.45m)=260.75 Joules
- To find the kinetic energy of the action, we multiplied Lindsey's mass by the velocity sqaured, and then divided it all by two(KE=1/2mv^2): KE=1/2(54.3kg)(3.20)^2=278 J
