For our physics of sports video we choose to do the sport running. In our video we show a good form and good technique to running. We also show that you can change your form from bad to good. We had two weeks to finish this project, we used 2-3 days to film all our videos and the rest of the time to film our audio.
We made an out line of our video with a small cartoon showing what we were going to do and say.( pictures at right)
We used many equations for find the angle, force, velocity, momentum and more. The equations we used were: mv=Ft which is relating momentum and impulse, a=v/t Which is used to find acceleration, h=½gt² This relates vertical distance and time. v=d/t This is used to find velocity. For this project we had to use many variables like accelerations velocity and momentum are a few. Here we will explain what they mean. Velocity is the rate of change an object has relative to it position. Acceleration is the rate of change of velocity speeding up or down, like how a car speeds up is acceleration or how gravity is pushing you down at (9.8m/s). M is meters and S is seconds so m/s is meters per second. Momentum is how much an object wants to keep going. How long and how forcefully something is impacted is impulse, momentum and impulse are equal to each other. Force is the push or pull on an object, like if you push a grocery cart in a store you are putting force onto it, Force is measured in newton's and a newton's is a unit of force. |
The equation we used to find what angle Jackson pushed of the ground with which was tanθ=(v horiz) / (v vert) where tanθ is the angle he pushed off with. We used vectors to form a right triangle, having V vertical going up and V horizontal across and finding the hypotenuses angle from c to b and the angle was about 9 degrees.
Over all I think the project was well put together. We had a plan from the start and we were easily able to achieve that without problem. I really didn't do as much work on this project, but that is because all the work was evenly divided among our group members. My team and I seemed to get along very well and cooperated very nicely and were able to satisfy everyone's needs. But I think there was room for me to improve I think I could have taken charge more than I did, I didn't put many ideas out there, next time I should throw them out there and not think that people will reject them. I could also try to let my team mates take charge sometimes and allow them to add more when they wanted to. Over all this project went really well and hopefully there will be others that will to.
