Well, the Olympics have been over for a few days now, but that doesn’t mean all the Physics angles 
have been covered. No one has yet talked about skate blades. The proper shape of a skater’s blades is crucial to their performance. Skates for different sports are all different. Hockey, speed skating, figure skating–they all have their own shapes.
Skaters use the edges of their skate blades to push against the ice, which then pushes back against the skater to provide forward movement. Also, blade pushing of the ice means a skater can apply more pressure to go faster. However, blades are not just straight pieces of metal, they are curved gently on the bottom edge. Many other distinct characteristics of blades are also noticeable. Read more about this here.

This article also say that: the more blade there is pushing against the ice the more force the skater can apply against it. The more force the skater applies, the faster the skater can go. The blades are not just small sheets of metal like I thought they were. The blades are individually designed for speed. Blades are shaped to curve gently along the bottom edge, which is called the rocker. The article says that the figure skates that are used have a toe pick in the front to help grip the ice and launch skaters into the air for jumps. In conclusion, there are many physics related things that are involved with the Olympics. Skating has many things involved with physics even down to how the blades are crafted.
