Cutnell & Johnson PHYSICS 6/e
Chapter Nine: Rotational Dynamics

Blocks and Center of Gravity

By Fu-Kwun Hwang, National Taiwan University, Department of Physics.

The classic physics demonstration and problem: four uniform blocks on the top of the table. How far can the blocks be extended and still remain stable?

The Physics of Dance

By George Gollin, in the Department of Physics, University of Illinois at Urbana Champagne

Figure-intensive slide presentation discusses torque, angular momentum, center of gravity, etc. This work was inspired by Kenneth Laws' The Physics of Dance.

Rotational Motion

University of Guelph Department of Physics.

A tutorial on rotational motion that includes torque, angular acceleration, rotational equilibrium and Right Hand Rule. There are sample problems and a self-test. This tutorial is part of the Physics Tutorials at the University of Guelph, Dpearment of Physics

Conservation of Angular Momentum in Skating

By Deborah King, Ellen Kreighbaum, Carolyn Petrie Sharp, & George Tuthill at Montana State University, Bozeman MT

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.
