  1. Figure skating By : Nicole Hanlon 6th hour science Mrs. Ewald

  2. Momentum • Momentum -how much force it takes to stop a moving object • When the skater is rotating in the air their angular momentum is conserved • however much angular momentum the skater generated during take-off (by applying forces to the ice), he or she cannot change it in air • a skater starts with their arms out. • That way they have more momentum and speed for revolutions

  3. Velocity • Pushing off the ice generates vertical velocity. • it gets a skater high enough in the air to do a spin by producing forces from the jump during takeoff. • The more velocity a skater has at takeoff, the higher and farther their jump • This is called Law of Projectile Motion – the more velocity you have at takeoff, the higher you’ll jump.

  4. friction • A blades has three feature: the rock and the two edges. • equal and opposite forces of the ice acts to propel the skater forward with kinetic energy. • Smooth ice- provides little resistance against objects • Low level of friction on ice allows skaters to glide along the surface smoothly without friction stopping them

  5. speed • They need enough speed to get in the air • Otherwise would fall on their face
