This is part of the Winter Olympics: Sports & Science course at MSU, which uses examples from winter sports to learn about science including physics and biomechanics. Figure skating is used to demonstrate the concepts of projectile motion and conservation of angular momentum.The site includes problems based on videos clips and solutions.
