... If you work out the units for this then: W=Nm = Joule (J) The joule is named after physicist James Prescott Joule and is define so that 1 Joule of work is done when a 1 N force moves an object 1 metre. Work is only done if the object is actually moved. Work is also the area under an F vs. d graph. W ...
