CURVILINEAR MOTION: NORMAL AND TANGENTIAL …
tangent to the path and the n-axis points toward the center of curvature. The plane containing the n and t axes is called the osculating plane. A third axis can be defined, called the binomial axis, b. The binomial unit vector, u b, is directed perpendicular to the osculating plane, and its sense is defined by the cross product u b = u t x u n.

Physics 1120: Angular Momentum Solutions
www.kpu.caThe 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, ...
