Comparing Real & Synthetic Ice

Synthetic ice is a popular, low-cost alternative to real ice rinks. Available in several forms and quality levels, synthetic ice usually consists of a slippery plastic surface which mimics the performance of real ice. 

How good is synthetic ice? The following graphs, excerpted from Glide, Spin, & Jump: The Science of Ice Skating: Volume 1: Extended Edition, compare the performance of a sharpened figure skate on real ice and HDPE synthetic ice.

Discussion Questions

1. Compare the force line in each graph, using words. What is one major qualitative difference between the graphs? 
2. In the second graph, what is the minimum force? Is the real force ever less than 0? Why or why not? 
3. Why is force applied before the skate moves? Does this force contribute to velocity? At what point does force contribute to acceleration and velocity? 
4. In the first graph, what is the maximum force? The maximum position? Velocity? Acceleration? 
5. In the second graph, what is the maximum force? The maximum position? Velocity? Acceleration? 
6. In each graph, calculate the range of time in which skate movement occurs. Which is larger?
7. The second graph claims that the skate has been pulled 1 meter. What is the evidence for or against this assertion? (Hint: How long is the skate?) 
8. What force is required to pull the skate 1 meter on synthetic ice? On real ice? Which force is larger?

A simple demonstration of one type of synthetic ice is available below, in the YouTube video My First Ice Rink. This synthetic ice consists of High Density Polyethylene (HDPE), one of the least expensive surfaces manufactured in the USA. In fact, 3/16" x 48" x 96" HDPE sheets from US Plastics Corporation sold for approximately $2 per square foot in 2014. 

While high-quality synthetic ice may cost $16 per square foot or more, one variety of Ultra-High Density Polyethlene (UHDPE) is available low-cost from Dezhou Shengtong Rubber & Plastic Co., Ltd. in China. According to price estimates in February 2015, an Olympic-sized synthetic ice rink (100x200 ft, UHDPE with sideboards) is available from China to East Coast USA w/shipping (not including import tax) for only $22,000! 

Additional videos demonstrating HDPE synthetic ice are available on the Skating Science Playlist.

Sliding on Ice: The Case of Two Hockey Pucks

The concept of friction is essential to all skating on ice, whether it is for hockey, speed, or figure skating. Ice provides a reduced-friction surface, which allows humans to glide, rather than stick to the floor. Synthetic ice, consisting of slippery plastic, also reduces friction. The friction of synthetic ice can be lowered further by applying soapwater, or other slippery liquids.

For gliding motion to occur, two types of friction must be overcome: initial non-moving (static) friction, and moving (kinetic) friction.

The following graphs, excerpted from Volume 1 of The Science of Hockey, show the effect of force on motion of an official hockey puck.

Discussion Questions

1. Describe the magnitude of each force in Graph 1. For what amount of time is each force applied?
2. Describe the motion of the puck in Graph 2, using words.
3. How far does the puck travel? In what direction?
4. Are the graphs coordinated in the time dimension?

The following graphs, excerpted from Volume 1 of The Science of Hockey, compare the force required to move two types of pucks on synthetic ice (HDPE plastic).

Discussion Questions

1. Is the total force different in these two graphs? If so, why?
2. Is the initial force different in these two graphs? If so, why?
3. What is the average force is applied to each puck?
4. Calculate the work involved for each puck.
5. Why does the practice hockey puck perform differently on synthetic ice than an official puck? (Hint: The practice hockey puck is normally used on concrete floors.)

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.

Pucks & Balls: The Physics of Motion

How does a ice hockey puck compare to a field hockey ball? This question is highly relevant for ice hockey players, who are eager to keep in shape over the warm summer months. According to physics, balls do not act like pucks. The graphs below (Copyright 2014, All Rights Reserved), excerpted from the book series The Science of Hockey from Schottenbauer Publishing, show an official field hockey ball and an official ice hockey puck in motion.

Discussion Questions

1. What is the range of each variable in each graph? Include x, y, and t as variables in your analysis.
2. Use the information from the graph to draw the trajectory of the ball and the puck on separate pieces of paper. Include beginning and ending time points in your drawing.
3. Using the information from Questions 1 and 2, compare the graphs. What is different about the motion of the ball and the puck?
4. Approximately how much energy from the ball is lost due to friction? 
5. Approximately how much energy from the puck is lost due to friction?
