The Team: Chapain Williams, Simon Moattar, Ty Cubley, Luke Venezia
Overview For this project we were asked to take a certain motion in a sport we selected and break it down into the physics of the motion. We had two days to film our motion and around a week to edit and revise our video. As a group we decided we would take the three pointer, from basketball, to use in our video. Over the course of 4 weeks we worked on our physics of sports video. We started out by spending a day or two to figure out what we were going to do for our video and how to set it up. After we came up with that we spent a couple days learning different physics concepts such as total velocity, vertical velocity, horizontal velocity, and the force of impact. Before we went on we spent three to four days coming up with a storyboard and script for our video and editing it so that the voice overs and editing would be easier. We next spent two to three days filming our shots for our videos outside. After we got our shots, we spent the last week or so making and editing our video making sure it was as perfect as it could be. The weekend before it was do, we shared the video with our class so they could give us feedback on our video. We spent our last day making the changes to our video that our class said that we should do.
Our finalized draft of our physics of sports video
Physics Concepts
Distance(d)- The amount of space between two points. The unit used for distance is meters(m).
Time(t)- The length of a pause or duration of or between events. The unit used for time is seconds(s).
Mass(m)- The amount of matter in an object. The units used for mass are kilograms(kg).
Force of Impact(F)- Something that causes a change in the motion of an object while the object is in contact with it. The equation is mv=Ft, and the units that are used are Newtons(N).
Horizontal Velocity(Vhoriz)- A measure of speed in a horizontal direction, and requires magnitude are needed to define it. The equation for horizontal velocity is Vhoriz=change in dhoriz/chamge in t. The units used for horizontal velocity is m/s.
Vertical Velocity(Vvert)- A measure of speed in a vertical direction, and requires magnitude are needed to define it. The equation for vertical velocity is Vvert=change in dvert/change in t. The units used for horizontal velocity is m/s.
Potential Energy(PE)- The energy possessed by an object when it is not moving. The equation that is used for potential energy due to gravity is PE=mgh. The unit used for potential energy is joules(J).
Kinetic Energy(KE)- The energy possessed by an object when it is moving. The equation that is used for kinetic energy is KE=1/2mv^2. Kinetic energy is also measured in joules just as potential energy is(J).
Gravity(g)(ag)- A force emitted by Earth that pulls matter towards it. The acceleration caused by this or acceleration due to gravity is 9.8 m/s^2. Acceleration is measured in m/s.
Total Velocity(Vtotal)- It is the total velocity of the object through the air. The equation for this is a^2+b^2=c^2 you substitute the horizontal and vertical velocity into a and b and solve the equation, and c is your total velocity. The units used for total velocity is m/s.
Script
The three pointer, we all know its hard, so how do the pros make it look so easy? Well it all comes down to the physics. Here is our team mate Ty Cubley shooting a three pointer. Let’s take a closer look at his form. The hoop is exactly 10 feet high or 3.04 meters, which is the 1.15 michael Jordans. Ty takes his shot from the three point line which is 23.75 feet from the hoop or 7.23 meters. The mass of the ball is 0.625 kilograms which later plays into our velocity and force of the ball. Now let' talk about his arms. he starts out with his arms holding the ball at his sholder level he then brings his arms up above his head with slightly bent elbows. He uses his non dominant hand to hold the ball steady while he uses his dominant hand to apply force to the ball. He flicks his wrist causing the ball to spin with a backward force and go sailing into the hoop. Next we have the velocity of the ball. Since the ball’s path is a curve we have to find three velocities. Total, horizontal, and vertical. Our horizontal velocity was 2.62 m/s. Our vertical velocity is 16.6 m/s. We then used a2 + b2= c2 to find our answer to the total velocity, which was 16.8 m/s. The last element of our physics that we found was the force of impact, which was 262.5 newtons. That’s equal to the weight of 39 full grown st bernards.
Reflection
Working on this project was quite a new experience for me since before this I had had very a minuscule understanding of video editing. It really made me appreciate the guys who do video editing as a job. Overall I think the video came out relatively smooth and professional looking, but it had its flaws. I think that one of the downsides of our project was that it got sloppy towards the end. We started out at a good pace and knocked things out pretty quickly, but once we got to the end of the project we started to slow down and get off task causing work to build up. In the end I think that I could've managed my time and my groups time better as a leader and group member. I also think that I could've tried to cooperate with my group a bit more. Once we started to get off task, and started to fall behind I started to blame my group members for it and try to avoid the blame. I now realize that in order to work well in a group setting you need to accept your mistakes and learn from them, even if they were not your fault. Although, the project didn't go a smoothly as I wanted it to it still turned out pretty good. I think that the best part of this project that worked was the editing. Throughout the editing phase it really taught me to keep an open mind about things even if it sounds boring. I learned a great deal about video editing and can now easily edit a video in several different ways. Last of all, I think that the filming process went well to it taught me a lot about different angles and ways to film things. One the members in my group, Simon Moattar, was experienced in shooting videos, and taught me several different ways to film a video, this really showed me that all team members have something to bring to the table at some point.
