About
How does an ice skater rotate so effortlessly on ice? What are the forces at play? How do they keep spinning? And more importantly, how do they stop? The tracks on this album use a variety of sports ranging from Ice Skating to the Highland Games to illustrate the nature of rotating bodies, looking in turn at torques, angular momentum and the moment of inertia. This material makes up part of the course MST209, Mathematical methods and models.
Torque and Momentum
An introduction to rotating bodies, focusing on baton twirling. Sport scientist Dave Cogner explains the relationship between torque and angular momen...
Spinning on Ice
A look at how ice skaters can control and change the speed of spinning, with relation to body mass and axis of rotation.
Diving
Angular momentum in Diving - rates of rotation, the moment of inertia, and the angle of momentum.
The Highland Games
The highland games provide a perfect background for studying the basic laws of rotational motion.
