Because i am an athlete, i really enjoy being outside and being active. Even in the winter, i like to be outside and the other day i was walking by the town hall and i saw the ice rink. There were some pretty good skaters on there, in the corner i see someone making figure eights, just like a professional ice skater would do. I always have admired ice skaters, especially those in the winter Olymics, they are able to turn so quickly in a certain amount of time. One of the units that we have learned in class is frequency, which is the number of revolutions completed in one second. When you watch a professional ice skater you think that they are doing one revolution in one second, when in reality they are doing three revolutions in one second. To find their frequency when turning we would divide the number of revolutions they have done by how long they continue to spin. They also apply angular momentum which characterizes an object's resistance to change in rotation. When they are rotating they apply a force called a torque it helps speed things up. When an ice skater brings their leg up while spinning, they apply anuglar momentum .
