Select the correct statements regarding moment and torque. (Select 3) Moment and Torque are two different phenomena, hence SI- units are different Generally Moment is used when there is no rotation, while torque is used when there is rotation. Moment and torque are very similar concepts and are sometimes interchangeable Moment and Torque are calculated by force multiplied by its distance to the reference point.
