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, ...

AP Physics 1- Work, Energy, & Power Practice Problems ANSWERS FACT: The amount of work done by a steady force is the amount of force multiplied by the distance an object moves parallel to that force: W = F x cos (θ). The units are N. m, which equal a Joule (J). Positive work is done by a force parallel
