Physics of Sports Video
Project Overview
Mr. Pitti, the athletic director at San Marin,wanted us to create Physics of Sports videos so we can educate the players about the physical concepts of a variety of sports and to improve technique to create a strong San Marin athletic program. My group picked the sport lacrosse, but the specific action of the fac eoff.
In the lacrosse face off, two players midfield players on different teams meet in the middle of the field and go intoa crouching position with the ball placed in between their two sticks. The referee blows the whistle and the two players try to scoop up the ball to gain possession. To do this, you have to prevent the other player from getting the ball while also trying to gain possession of the ball. The person who can clamp the ball and thrusts it to their side and away from the other player so another midfielder on the same team gets the ball. The face off is very essential to the fate of the game.
Our two primary focuses during this project were to calculate torque and force. Force is a push or a pull. Torque is the tendency of a force to rotate an object around a fulcrum, an axis, or a pivot point. To measure torque, you must multiply the force applied by the measure of the lever arm. To calculate force, you must take the mass times the acceleration of the object. To measure the acceleration of the object, you must divide the velocity by the time traveled. And to find the velocity, you must divide the distance traveled by the time traveled.
Since the head of the stick is placed perpendicularly to the ground, it travels in a quarter-circle path. The distance is taken by the equation C=1/4_d. We end up with a distance traveled of 27.17cm. To find the time traveled, we timed Nick flipping his stick from starting to finishing position during a face off with Cole. We ended up with an average of 0.272cm. We come up with a velocity of 0.998m/s.
To find our acceleration, we divide the velocity by the time traveled, and come up with 3.67m/S2.
To find our force, we take the mass of the head and multiply it by the acceleration. Our force is 0.652 Newtons.
To find the torque we multiply this force by the radial distance of the lever arm, 8.65cm. We have a final torque of 0.0564 Nm.
Concepts:
Momentum: the quantity of motion of a moving body, measured by multiplying its mass and its velocity.
Rotational Forces: (torque) the tendency of a force to rotate an object around an axis, fulcrum, or pivot point.
Torque: (see Rotational Forces)
Friction: the resistance that an object or surface encounters when when moving over another.
Velocity: speed in a given direction.
Acceleration: change in the rate or speed of an object.
Projectile Motion (Horizontal Velocity): the rate of change of position (velocity) of an object moving horizontally.
Impact Forces: a high force applied over a short time period when two or more bodies collide.

I really enjoyed this project, I mean it did exactly what it was meant to do. It increased my understanding and knowledge of the physics concepts we learned in this project. I enjoyed learning better ways to film and editing techniques, which I will definitely use in the near future and our next projects. I think our group, Natalie Mansergh, Bronte Hoefer and I, worked very well together. There was not one fight what so ever and we worked very well and efficiently. We helped each other out especially when if there was any spare work to pick up or something to get done we would all try to help. We could have, however, worked on time management a little more. Rather than planning out our days and working on a schedule, we'd frequently work the first period, about an hour, and slack off and do nothing in the second period. These little periods of time could have easily been used to edit work or script or film, but we just decided that we were too lazy and did not use them to our advantage. That being said, the time we did work was used rather efficiently, for the most part, and in the end we came up with a fantastic video that I am proud of.
Most of the work I did focused on editing, filming, explaining lacrosse to my group, and doing math and some scriptin. It was challenging to make our explanation in a way that made it easy to understand and flow nicely together, as well as meeting the time limit. This project I really learned to discipline myself more and focus on just one task that needed to be done rather than running around and trying to juggle every element of the project at once. I have definitly learned that I seriously work more on time management and being on task and focused more.
Our group collaborated really well and I think that in the end, we created a product that we're really proud of (maybe a little too much) and that we really enjoy watching. This project was great. It taught me about how physics is used a lot more often than I really thought. Overall, this project was extremely fun and exciting.
