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.

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

Cite used: http://thwink.org/sustain/glossary/LeveragePoint.htm

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.

 

Post 1 Module 2 (How the length of your stick can affect your shot)

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”.

Module One Post Fifteen (hockey goalies)

video used:

In this video, sports science (company) wondered rather than having athletic goalies in net, if they put a big goalie in net that covered over 90% of the net, would they stop a shot of over 70mph? They’re results clearly showed that a athletic goalie is better than a big one, this ties in with reflex and reaction time. As it is a key in the game of hockey. I found this video very informative and entertaining. A great video, demonstrating that size/mass is not a big factor.

Module One Post Fourteen (reaction time)

video used: 

In this video, they compared reaction time between a cat and a goalie. It was shown using professional hockey players, both goalie and player. The goalie can react use as fast as a cat, however for the goalie, it was not a reaction it was a reflex. Human are not capable of reacting 1/10 of a second however they can follow the puck and know where about it is located. Overall a cool and informative video, displayed and explained very well. Definettly recommend to others!

Hockey takes advantage of one of the most precious liquids in the universe, water. Water is used as ice in it’s solid form. A hockey rink is 200 feet in length and 85 fee wide, therefore takes around 10,600 gallons of water to fill to about an inch. However, water expands when solidified, thats why some pipes break. This is how zamboni’s play a huge roll in the process of maintaining ice. It first removes first layer of ice, then puts new coat of water after finished. Therefore removing solids/refurnish ice before next period. This will be helpful when looking at the rink and it’s design. An amazing source of information!

Module One Post Twelve (Energy in hockey)

Cite used: https://science360.gov/obj/video/c5be5456-2e39-49a7-8118-218868df89eb/work-energy-power

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.

Module One Post ten (Hockey math)

Cite used: http://spinnakers.org/mathonice.htm

In this cite it displays many key examples of how math is implied in the game of hockey. For instance, if you are shorthanded the fraction would be 5/4, meaning the opposing team has five and you have four. A great demonstration of fractions which is used practically every game. Another example is when angling someone to the outside of the boards. You want to cut them off from an angle so that they run out of space, this is a key aspect for defensemen like me. We are told and use this strategy on all times when the opposing team is rushing in. Lastly, the triangle, this shape is commonly used as a direction of offence, players (forwards) will shape up in this formation in the offensive zone creating good passing lanes. In all i found this extremely useful, as it is filled with a lot of information and examples. Definitely recommend to anyone!

Module One Post nine (Ice skating)

Cite used: https://www.real-world-physics-problems.com/physics-of-ice-skating.html

This website goes over an important aspect of the game of hockey, skating. In this website it reviews the two motions of the skate a push from the edge and then a glide. Not only that but doing movement on ice is near friction less therefore top speeds of over 40 kilometers can be reached with quite ease. In addition it goes over the relationship between force and speed. Similar to running one foot pushes and one foot glides, therefore having a good balance and a straight line of direction. In my opinion, this website has very good and relatable information. It easy to understand, and will be definitely used in my research.

Module One Post Five (Shooting)

Cite used:https://physicsofhockeyproject.weebly.com/shooting.html

This website provides basic knowledge of the form, mechanics and projectile motion of shooting a puck in hockey. In addition, it shows what happens if you miss the shot. Unfortunately this site does not have too much information. This for me will be used more as reference page rather than a research page. Although may gather some important data, as i found some information extremely interesting. Definitely going to come back to this site again!
