Figure Skating Figure skating is an Olympic sport which individuals, pairs, or groups perform intricate and challenging moves on ice skates It is a fun and relaxing activity Figure skating is a good sport to see physics in action Michelle Kwan >

Physics of Figure Skating Friction Angular Momentum Newton’s Third Law Collage of figure skaters >

Friction Friction is the force which resists when 2 objects slide against one another The rougher the surface, the more friction occurs The ice is smooth, so there is little friction between the ice and the blades of the ice skates

Friction (continued) Low level of friction on ice allows a skater to glide along the surface smoothly without friction stopping the motion as soon as it's begun The small amount of friction also allows ice skaters to stop whenever they want to Sasha Cohen ^

Angular Momentum A quantity that can be used to describe the overall state of a physical system To perform a spin or jump with several rotations in the air-needs to generate angular momentum The skater applies a force against the ice, the ice then applies a ground reaction force on the skater This ground reaction force causes gives the skater angular momentum

Angular Momentum (continued) The point of application and line of action of angular momentum is critical If the line of action of the force is directed through the skater's axis of rotation, then she won't spin Mao Asada ^

Newton’s Third Law For every force applied there is an equal and opposite reaction Push off against the ice-applying a force down and back against the ground Ice pushes right back, supplying a force forward and up that propels the skaters into a glide or jump, depending on the particulars of the force they applied
