Torque is to force as moment is to mass.
Just as the mass determines how much force is needed to move the thing - the moment of inertia determines the amount of Torque necessary to twist the thing.

A torque is simply a twisting force. When you unscrew a cap from a bottled drink, you are exerting a torque.
A moment is just another word for a torque, more common in engineering fields.

The main concept of torque is that there are force couplets (vectors) that cannot be resolved into a resultant, resulting in, as the previous poster said, a twisting effect.
The simple explanation of moments is that they involve a force acting through a distance, as with a lever.
