For 10 points, identify this quantity which describes the tendency of a a force to cause rotation about a fixed axis.
Gyroscopic precession may be induced by or free of this physical quantity, which is dotted with angular velocity in one expression for power. It is measured in units equivalent to joules but named differently, as newton-meters. This quantity is calculated as (*) radius cross force, with its direction found using the right-hand rule.
