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