We have been talking about the winter Olympics in physics the last few days and when I think of the Olympics the first thought that pops into my brain is brrr that's cold. The next thought is how I always admire the ice skaters and how 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 their sequence is. 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.
