Topic: Figure Skating

Our Questions:

How to figure skaters spin so fast?
Does the placement of their skates correspond with how fast they spin?
Will the figure skaters spin faster if the ice underneath melts faster?

Will the body heat and other heat sources from spectators effect the skater's overall performance on the ice?
Does the type of blade effect the speed or balance
of the ice skater?
How does ice skating work?



Research Notes for Sabrina: It is unsolved right now why ice is slippery many scientists disagree over this seemingly simple question. Ice has very little friction which could be one of the reasons why ice is so slippery. Since ice has such low friction, ice skaters can continue to be in motion until they exert a certain amount of force to stop. However, without friction ice skating would be impossible for us today. The law of physics explains that momentum is always conserved unless a new outside force enters momentum must be constant.

Research Notes for Emily: Figure skaters spin faster by tucking their arms closer to their body. They spin slower by stretching their arms out in front of them.Figure skaters build momentum before and going into a spin and this allows them to move their body into different shapes as they spin.​​The blade of an ice skate creates friction between it and the ice. By creating friction, the ice melts and the skater is actual creating and skating on little beads of water from the melted ice. The thicker the blade of the ice skate the faster the ice will melt and the quicker they will move, the more momentum they will gain, and the faster they will spin. When you skate, your velocity changes and allows you to go faster​. When you skate, the blade rubbing the ice allows you to accelerate. When you spin, the constant changing direction allows you to accelerate. When you pick the tip of your blade in the ice, it is potential energy waiting to be converted to kinetic energy when you jump. Before you jump, you push off and bend down to build height. The average temperature of the surface on the ice in an ice rink is about 24-26oF.


Vocabulary:

Stroke- a push of an ice skate
Acceleration- the change of velocity over time
Gravity- the force pulling down on you
Newton's 1st Law of Motion- an object at rest will stay at rest until acted upon by another force; an object at motion will stay in motion until acted upon by another force
Newton's 2nd Law of Motion-
Newton's 3rd Law of motion- every action has an equal and opposite reaction

Things We Need:

- Answer our questions
- Find a video demonstrating the physics in action *

Things We Have Done:

If you complete something in the list above, cut and paste it from that list to this list.

Project Planning:

We could do a model and make an ice rink with two figure skaters. One of the figure skaters could have his/her arms tucked in and one could have their arms stretched out. We could also make a powerpoint or poster explaining what is happening in the model and how science applies in ice skating.
