By definition, Moment is a quantity that represents the magnitude of force applied to a rotational system at a distance from the axis of rotation.Mathematically, it can be represented by a cross product of a bound vector vec{v} at a position vec{r}
When 2 equal and opposite forces are applied through a distance, the resultant sum of vectors is zero. It is also referred to as a couple.
Therefore, Torque can also be called as the moment of a couple. This implies that torque is a special case of Moment, such that it relates to the axis of rotation driving the rotation, while moment relates to being driven by external force(s) to cause the rotation.
