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.
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.
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.
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”.
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.
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!
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.
This resource comes from a site already mentioned, however i am just further explaining each video. This video here defines what kinematics is and how it is applied in hockey. First kinematics is the way to define a moving object by position, velocity and acceleration. Position is where located on the ice, velocity is the speed/aggression in the strides. Lastly acceleration is the calculation of standstill speed to top speed which most NHL players can hit around 30 miles per hour. In all this is a very handy website, with very informative and true information. An extremely reliable site that will help me throughout the project.
