Homework Help: Difference between torque and work

  1. Apr 24, 2013 #1
    What is difference between Torque and Work Done if Newton-Meter is Joule?

    Torque=Force*Perpendicular distance Work =Force*displacement

    The units for torque and work happen to have the same dimensions but torque and work are very different concepts. Work is a scalar and torque is a vector.

    The angular equivalent of work = force*displacement is:
    work = torque*angular displacement

    where angular displacement is measured in radians, which is dimensionless, so the unit for torque must necessarily have the same dimension as the unit for work.
