Uh, no. SI unit of Force: newton Torque: newton meter The dimensions of torque are also the dimensions of work (force x distance) The difference in physics is the orientation: work is the product of the component of the vector force parallel to the displacement torque involves the force perpendicular to the displacement vector (relative to some origin) neville_black ( at ) cable.comcast.com
