Main article: newton metre
In angular mechanics, torque is akin to the beeline Newtonian mechanics constant of force, moment of apathy to mass, and bend to distance. Activity is the aforementioned in both systems. Thus, although the joule has the aforementioned ambit as the newton-metre (1 J = 1 NВ·m = 1 kgВ·m2В·sв€’2), these units are not interchangeable: the CGPM has accustomed the assemblage of activity the name "joule", but has not accustomed the assemblage of torque any appropriate name, appropriately the assemblage of torque is accepted as the newton-metre (NВ·m) - a admixture name acquired from its basic parts.[5] Torque and activity are accompanying to anniversary added application the equation
E= \tau \theta\
where E is the energy, П„ is the torque, and Оё is the bend confused (in radians). Since radians are dimensionless, it follows that torque and activity accept the aforementioned dimensions.
The use of newton-metres for torque and joules for activity is advantageous in allowance abstain misunderstandings and miscommunications.[5]
An added band-aid is to apprehend that joules are scalars – they are the dot artefact of a agent force and a agent displacement admitting torque is a vector. Torque is the cantankerous artefact of a ambit agent and a force vector. Drawing a acceptable agent arrow over "newton-metre" in a torque resolves the ambiguity.
