Hey guys, I've just started my first year of Physics in High School and so far, it's really interesting! Great too see just how everything around us actually works! Anyway, I've got a question for everyone. To introduce us to Physics and better acquaint ourselves with the world, our teacher is making us do a project on the physics of our favorite hobby, and my favorite hobby just happens to be Martial Arts, so I decided to do the physics of a certain type of kick called a jumping spinning crescent kick. If any of you do martial arts, you should know what the kick looks like, and if you don't, here's a tutorial of it. http://www.trickstutorials.com/index.php?page=content/t_360 Any help you guys could give me would be greatly appreciated!
