public class Torque
extends Quantity

This class represents the moment of a force. The system unit for this quantity is "N·m".

Note: The Newton-metre ("N·m") is also a way of exressing a Joule (unit of energy). However, torque is not energy. So, to avoid confusion, we will use the units "N·m" for torque and not "J". This distinction occurs due to the scalar nature of energy and the vector nature of torque.
