Module One Post Fifteen (The Physicist Who Figured Out Ballet)

This website explains how ballet is related to physics. This site had a lot of really good information and great explanations. It explained which moves involve physics as well as how to apply it. Kevin Laws is the author of this article, he is actually a ballet teacher now, and he has written three books. He says it’s important that ballet dancers see the value of scientific perspective. He says that dialogue between science and ballet can produce concrete results. He also explains that there is so much more to ballet than just strong toes and practice.

This website was helpful because the author gave multiple examples of how ballet involves physics, as well as real stories as to how he explained to his students the involvement of physics in ballet. This article also taught me how to apply this while I’m doing ballet.

Post 5 Module 2 (How the length of your stick can affect your shot)

ĀCite used: https://www.real-world-physics-problems.com/physics-of-hockey.html

Before researching further, I must know how the hockey stick is used and the physics behind one to evaluate a shot. This site provided a detailed look at a slap shot and speaks about an important aspect of a shot, weight transfer. Weight transfer is the ability to translate movement into power. In this case, power goes to your stick causing it to flex. However it is harder to utilize this movement if the stick length is not properly fitted or flex is not proper. This cite also discusses about the different curves on the blade and how it benefits your shots. In conclusion, this is a great website that informs a lot about the physics found in a hockey shot.

Video used:

This video provides information when purchasing a stick. Therefore the different sizes and flex. It also shows a graph on height to stick based on your body physique (weight and height). This is an reliable source of information, however I do know certain people who do not follow this rule of thumb, and do just fine. This is something i would like to test too, if the flex of the stick affects the top speed of your shot even if both sticks are the same height. This source will be more a reference when doing our experiment.

Video used:

This video was done by a renowned hockey tutorial channel, explaining some benefits and disadvantages between long and short sticks. Focusing on the shot aspect, he says that the shorter the stick less power, however bigger the stick harder the shot. Although i disagree, as the long stick in the video was was designed for a 7 foot tall person. In result, when contacting the puck there will be less power and accuracy. This is a good video to question, that I can further test throughout my project.

In this website, it demonstrates the scientific definition of what leverage is. In science, leverage is the ratio of change in output to the change in input. The equation to calculating leverage is =leverage x force = change. In other words, leverage multiplied by the amount of force is equal to the change. This website also discusses four MAJOR terms to know:

Change force: Effort required to prepare and make a change

leverage point: Place in structure where a solution element can be applied

low leverage point: small amount of force causes small change

high leverage point: small amount of force causes big change

In all, a great site reviewing and analyzing the definition of leverage.

Cite used: http://hfboards.mandatory.com/threads/thoughts-on-stick-length-leverage-and-stick-flex.2362981/

This website, is a theory/opinion based on stick flex and length. This opinion is gathered through experience and questioning. Flex is how much weight is required for the stick to flex an inch in the kickpoint. His opinion is that when cutting a stick of for example 100 flex, when cut shorter the flex doesn’t change, however it feels stiffer as the player can maintain less leverage when shooting. He also believes that flex can vary through the girth of the stick too.This is something we must consider while doing our experiment, the stick flex and height. In all, a bit more detailed look and opinion of stick length, and also mentioned an extremely important term “leverage”.

Leaning Tower of Pisa Facts

                               

The leaning tower of pisa in Italy seems like a miracle that is defying gravity`s pull. Since gravity force would be greater on objects with greater mass, it is fascinating how pisa tower is still standing with an approximate mass of 14,500 tonnes! Physicists predict that the tower would fall when its leaning angle reaches 5.44 degrees, but the pisa tower has been seen to reach an angle of 5.5 degrees before restoration work has been done between 1990 and 2001. With advancing technology in engineering and architecture, the tower is now standing at an 3.99 degrees angle. This helps with preserving this amazing architecture piece for another few hundred years or even longer.

Module One Post Twelve (The rule of thumb)

The rule of thumb

This website explains the reason why things decrease in velocity when they go on a flat surface. It’s because of the rule of thumb. The rule is that when a object is slowing down, the direction of the acceleration is in the opposite direction object’s motion. The diagram below shows this process. The green arrow indicates the direction of the velocity and the green arrows indicates the direction of the acceleration. When you ride in a car and you come to a urgent stop at a red light you can feel yourself leaning forward. Your motion is forward but you are negatively accelerating, or slowing down.

Once again breaking down another video from one of the previous mentioned cites, this video is about a theory of physics. A slapshot, one of the best representations of the game of hockey is a great example of the physic theory of work, energy, power. Energy is the power that will accelerate the puck. Both kinetic and potential energy could be used during a slapshot. Kinetic is the movement of energy, for example weight transfer or even a swing from your arm. Potential energy is the energy stored in a object, for example a hockey stick. Work is when force hits an object therefore displaces it, in this case the puck. Lastly power is the amount of work done overtime. In all, this cite will be extremely useful, because i believe this will be a good guide for me in the long term during my project.

I found a site with information on how ballet is related to physics. Ballet involves physics and this site had a lot of information. It explained which moves had physics and how to apply it. It was written by Kevin Laws who is a actual ballet teacher now and who wrote three books. He explained that ballet is much more then practice and really strong toes.

This site helped me because there were multiple examples on how ballet involved physics. Most sites just list one example but this site had multiple. I can also apply this while I’m doing ballet, and I can understand it better if I had my own experience. But overall this was a very helpful site.
