Physics of Sports Video
Evidence of Work
After we finished our Rube Goldberg Machine projects, we began working on our Physics of Sports projects. The first thing we did was make a script of what is going to happen in the video that we would be making. We spent about two days making the script for our videos and then we began production. For my group, we chose to do hurdles; but that ended up not working out because we didn't have access to actual hurdles, so instead, we did chair hurdles. We spent a week in total of us recording and figuring out how our group wanted to make the video. Afterwards, we did the calculations for the physics of the hurdles and that took us 2 days. Finally, we had 3 days just to purely edit our videos. In the end, our video turned out pretty short but I think that it has everything it needs to be a good Physics of Sports video.
Reflection
This was by no means an easy project. For me, this project was the complete opposite of the last. What I mean by this is that in the Rube Goldberg Machine project, I needed to participate and work more. While in this one, it felt like I had to encourage my group to participate and work more. This ended up making me feel like I was doing too much of the work, but I didn't have too much of a problem with this because stuff was getting done. I soon realized that in group projects, you have to work as a group and that there's no exceptions for that. I learned this the hard way because when I was gone at a Water Polo tournament for the final editing day, I asked one of my group members by text what they had done in class that day and how the video was going. They told me that they did nothing because they were with their friend for half of the time while our other group member was playing games on their phone the whole time. This didn't help our case at all because we were in dire need of time to work on our video but that time had just been wasted. Thankfully though, one of my group members contacted me in the afternoon that day after school had ended and they said that they'll help edit the video. This was defenitely a huge help to our group and it was really nice of the that member to help edit even after school was out. What I've learned from this project and from working with my group is that it doesn't just take a leader to make a successful group, it takes everybody to make a successful group.
Concepts
Force- Force is the push or pull on an object(the weight). To find the Force of an object you use the equation F=ma(Force equals mass times acceleration) The unit Force uses is newtons which when written in an equation, is represented by N.
Speed/Velocity- Velocity is the rate of distance covered in a direction. The equation used to find the velocity of something is v=^d/^t(velocity equals the change in distance over the change in time). The unit used for velocity is m/s which stands for meters a second.
Unit Conversion- Unit conversion is the transfer of one unit to another while retaining the same amount. To convert inches to meters you use a ratio of 1(inches):(meters)0.0254. The unit you use for this is the newly converted unit.
Vertical Velocity/Landing Velocity- VV/LV is the rate of distance covered downwards or upwards. The equation used to find these
velocities is v=^d/^t(velocity equals the change in distance over the change in time). The unit used for VV/LV is m/s which stands for meters a second. Tip: when trying to find velocities with very little time, count the frames of the action you're trying to find the velocity of in the slo-mo video editor and divide it by the rate at which the iPhone recorded the video at(which is usually 24 or 30).
