1.) What is the relationship between angular momentum and a skaters' revolutions per minute when they spin?
The greater the angular momentum, the faster the ice skater will spin.
2.) How are the edges of the blades related to the types of jumps and spins that can be created in relation to their frictional force?
The blades often have toe picks on the front of them to increase frictional force along the skater to make jumps and spins possible. The normal edges of blades don't have enough friction to apply a great enough force to make spins or jumps, so there is a toe pick in place to create greater friction.
3.) What does the equation I1W1=I2W2 represent in terms of ice skating?
It represent the example of how an ice skater accelerates while spinning when they bring their arms closer to the center of their rotation.
4.) What does L=IW mean in relation to when a skater spins?
This equation is used in order to find an ice skaters angular momentum.
