Hi. I'll start off by saying I have a background in mathematics, but not in physics. If I use the wrong term, I apologize and I hope that you'll correct me. I am interested in buying new ice skates and I've been noticing that I can often select the length of the blade as an option (e.g. 30 cm vs 32 cm). As I'm skating along, I expect that means there's more transfer of energy occurring through the blade. Does this translate into an increase in my velocity? Thanks.
