013/**
014 * Moment of a force.
015 * The system unit for this quantity is "N.m" (Newton-Metre).
016 *
017 * <p><b>Note:</b> The Newton-metre ("N.m") is also a way of expressing a Joule
018 * (unit of energy). However, torque is not energy. So, to avoid confusion, we
019 * will use the units "N.m" for torque and not "J". This distinction occurs due
020 * to the scalar nature of energy and the vector nature of torque.</p>
