  2. Figure Skating • Figure skating is an Olympic sportwhich 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 >

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

  4. 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

  5. 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 ^

  6. 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

  7. 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 ^

  8. 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
