Physics 1120: Angular Momentum Solutions

The angular momentum of an object moving in a circle is r2mΩ, where r is the radius of rotation. At the centre of the disk r = 0, initially. At the final position, the edge of the disk, r = R. The disk is rotating and thus has an angular momentum by IΩ. Consulting a table of moments of inertia, ...

Three-Dimensional Rotation Matrices

The most general three-dimensional rotation matrix represents a counterclockwise rotation by an angle θ about a fixed axis that lies along the unit vector ˆn. The rotation matrix operates on vectors to produce rotated vectors, while the coordinate axes are held fixed. This is called an activetransformation. In these notes, we shall explore the
