[https://en.wikipedia.org/wiki/Archimedes '''Archimedes''' (c. 287 BC – c. 212 BC)] is reputed to have once said ''“Give me a place to stand and with a lever I will move the whole world.”'' This is because, when using a '''[[:Category:Levers|lever]]''', it is not only the force exerted which matters, but also the distance it is applied from the '''Fulcrum''' so a small force exerted at the end of a long lever can lift a heavy load.


A '''Force''' multiplied by the distance it is applied from a '''Fulcrum''' or other fixed point '''''(F x D)''''' is known as the [https://en.wikipedia.org/wiki/Moment_%28physics%29 '''Moment of a Force'''] - ''(often shortened to simply '''Moment''')''. The '''Force''' is measured in '''[[newton|newtons]]''' and the '''Distance''' in metres giving units for a '''Moment of Force''' as a '''newton/metre''' '''''(Nm)'''''.[[File:MeasuringTorque.png|300px|right]]


'''[[Torque]]''' is a measure of the effort need to turn or twist an object about its axis and so it too is a  '''Moment of Force''' measured in '''newton/metres''' '''''(Nm)'''''.
