The Physics of Sports Video
For this project we were matched up with new group members and tasked with making a video on a sport action of our choice. My group and I brainstormed ideas but in the end we decided to do running because not many people had done it for these videos before and it would be easy to film. In this video we had to explain how to maximize the efficiency of the action we chose and how to improve in the sport.
Physics
In the calculations for the project we used three simple units which were Mass, Time, and Distance. when using these units in equations we had to combine the terms into other units that are used in physics.
Acceleration due to gravity on earth is always 9.8m/s². Velocity (v) is the rate that and object covers a distance in a certain direction. Force (F) is anything that pushes or pulls on an object and is measured in Newtons (N). Impulse (J) is how long and how hard the impact of something is. Momentum (p) is the amount that an object will keep moving. If two objects hit each other, the relative Momentum is equal to the total Impulse.
We used these basic equation in this project:
v=d/t
This means that if you are trying to find the velocity of a and object by dividing the the distance by the time it takes to travel that distance. We used this to find the velocity of Jackson.
a=v/t
To find the aceleration of something you must divide the velocity by time. We used this to find the speed at which Jackson was moving at when he first started to run.
Δp=J (mv=Ft)
mv=Ft: Means that if you multiply the mass by the velocity to get the Force multiplied bet the time.
h=½gt²
This means that hight equals 1/2 the force from gravity which on Earth is always 9.8 m/s squared times the time squared. We used this to find the height that Jackson went on every step.
Reflections
In reflection i would say that this project was a lot better than the last one. Most of that was due to the fact that me and my group got along much better than me and the last group I was with. In this project I got better at taking more control and coming up with ideas that the group can get behind. I also learned more than I knew before about how to calculate the force of an object and how to find the acceleration and velocity of a moving object.
