Physics of sports video

Process of making the video:

To make our physics of sports video we first had to figure out what type of sports move we want to do. We ended up choosing the sports move throwing a football. Before we could even start throwing the football we have to make a story board plan first. We needed to make this so we know what to do. After making our story board it was time to start making the script. We needed to make sure the video was a good length so we could get our point across on how to throw a football. In our sports video we needed to explain the physics behind throwing the ball. We also had to explain all of our steps on throwing the ball. After we did all of that we were able to film. We needed to film various shots throwing a football and then serval other shots explaing steps such as, foot placement, hand place ment, and all the upper body movements. Then finally we needed to put all of the clips together and edit the video to get our final product.

If you don’t have the correct steps, this may be likely to occur when throwing a football. (Video of person throwing football incorrectly) 


Many sports, such as football, can be very dependent on physics. You need to make adjustments for different factors, such as distance, air resistance, and weight of the specific ball, when throwing a football. The farther away the ball receiver is, the more force you need to exert into the ball. This is only one example of many. The more you know about physics and how it relates to football the better you will be at doing it. 




The first step is foot placement and facing your body sideways. Your feet should be at the same diagonal as your shoulders. This is connected to physics and provides maximum velocity and momentum transfer. 


The second step is to get the right hand placement, you need to make sure that your fingers are on the laces and one finger is on the white line. Step two is also connected to physics because having your hands in the right spot will allow it to have a spiral which will cut down air resistance. 


Next you need to make sure your body is facing sideways so you can twist your hips. 

The next step is to raise your arm and tilt back your hand. You need to tilt back your arm for more power and to gain a higher velocity. This is also connected to physics because, cocking your arm back allows you to gain more power to throw it a further distance. It also helps with gaining momentum. 


Then you need to throw your arm forward to increase the power. Throwing your arm forward is connected to physics because it is an energy transfer from your arm to the ball. When you release, your arms potential energy converts to kinetic energy. 


The next step is twisting your hips while you throw. It is connected to physics because it gives you rotational force.


Then finally following through with your whole body is connected to physics because it will help gain a further distance and power. It will further increase the velocity as well. When you follow through, your hips twist, and your arm falls with the ball. 







8) In order to calculate for our elements, we used various different types of equations to gain a better understanding of the sport we had chosen. To find our vertical distance, which is the maximum height of which something falls, or goes, we multiplied ½ times the acceleration due to gravity which is 9.8 multiplied by the time (fall) squared. By using this equation, we calculated a distance of 3.4 meters per second. (11 feet per second.) 


Additionally, our horizontal velocity is the speed from side to side. In this case, we threw our football 10 yards horizontally. (9.14 meters) The equation for this would be the distance height, divided by time. From this equation, we found a horizontal velocity of 4 m/s (9 mph).


 To find our vertical velocity, which is the speed of the fall either going up or down, we multiplied the acceleration due to gravity by the time it took for our ball to fall. This gave us a vertical velocity of 8.13 meters per second (18 mph) . 


Next, to find our overall total velocity combo we used the pythagorean theorem. Our velocity horizontal squared, plus the vertical velocity squared would give us our total velocity squared. Using the pythagorean theorem equation gave us a total velocity of 9.05 meters per second. (20.2 mph) 


Our momentum is how difficult something is to stop. To find this, we used the equation of momentum =mass x velocity (Momentum equals mass times velocity). When calculating the momentum of the football, it was 3.09 kilograms per second. We could increase the momentum by throwing the football at a faster speed, with one that has a mass greater than 0.897 pounds. 


We also found our impulse by multiplying mass times velocity is equal to force times time. This gave us a force of 10.3 newtons, or 2.31 pounds. Finally, Our football had a mass of .407 kg, which is also equal to 0.897 pounds.

In the end we were able to successfully create our trebuchet and it worked really well. Two areas I think I did very well in for the 6 C's is I think I did very well with comminacation because I was able to easily commincate with my group mates and help out whenever they needed and coorapated very well. I also think I did good with critical thinking, I came up with some good ideas for the group that were pretty helpful. Some areas that I think I need to improve on in that area is,  Collaboration. I need to work more on this because I need to help out with building the trebuchet more and working together better. Another area is Concientious learner. I need to do better in this area because I wasn't understanding the some of the concepts very well.
