Video Analysis of "Cool Skating Move"

As with any sport, ice skating can be analysed in graphs. Consider the following graph below, excerpted from the upcoming Volume 9 of Glide, Spin, & Jump! The Science of Ice Skating by Schottenbauer Publishing. 

Discussion Questions

1. What body parts are moving in this example?
2. Which body part moves the most in the x direction? In the y direction?
3. What is the name of this move?

Now, consider the following pictures, excerpted from the video. (This move is shown in the YouTube Video Cool Skating Move.) 

Discussion Questions

1. Is this move in the first or second half of the graph?
2. What is the primary motion which occurs between these two pictures?
3. What concept(s) from physics are relevant for this move?
4. Is this move found in (a) figure skating, (b) ice hockey, or (c) both?

The diagram below highlights the move on the graph.

Discussion Questions

1. Which body part moves the most during this segment of the graph?
2. Which body part moves the most in the x direction? In the y direction?

Additional free graphs are available in a free pamphlet from the publisher's webpage.

How Does Geometry Affect Ice Skating?

On the surface level, both the technique and beauty of ice skating can be described by geometry, in terms of the angles of knee bends and arm positions. On a technical level, geometry is essential for understanding the science of ice skating, including the physics of force and motion.

The books The Geometry of Winter Olympic Sports and The Geometry of Figure Skating contain diagrams which introduce children and teens to the task of identifying angles in ice skating. Consider the diagram below, excerpted from page 25 of The Geometry of Winter Olympic Sports (Copyright 2014, All Rights Reserved).

Discussion Questions

1. How many angles are formed in this diagram?
2. From a casual analysis, what types of angles (Acute/Obtuse/Right) are located in the diagram? Indicate the location of each angle.
3. In order to analyze the angles in this diagram, where should the coordinate axis be placed? Why? Is it necessary to identify more than one coordinate axis? Why or why not? If so, where should the axes be placed?
4. Using a protractor, measure all the angles in the diagram that are relevant to the art or physics of skating.
5. Is it possible to identify the direction of motion from this diagram? Why or why not?
6. Is this a figure skater or a hockey player? Justify your answer.

Assistance answering some of these questions may be found by watching the video How to Use Geometry Workbooks on the publisher's YouTube channel.

The following books from Schottenbauer Publishing contain geometry diagrams relevant to ice skating, figure skating, and hockey.
