Chapter 10. Rotation

Supporting pages (HTML pages with embedded animations)

Background material on rotation
Rotational kinetic energy and the moment of inertia. Rolling vs skidding. Torque and Newton's laws for rotation. Angular momentum. Gyroscopes and precession. Includes Rolling Problems (with movies)

Wheels and rolling
The relation between angular and translational velocities for a rolling wheel. Motion of a point on wheel.
Circular Motion
Circular motion (uniform and nonuniform), centripetal acceleration, fictitious forces.
Newton's laws
Newton's laws of motion, inertial frames, the nature of mass and force, examples.
The vector product
The vector product defined. Calculation using unit vectors. Sign convention and the right hand rule.
Wheelies or wheelstands
What are the conditions of torque and friction under which an accelerating (or braking) car or bike could lift the front (or rear) wheels?
