This video explains the two different situations where the unit of measurement is the newton-meter. The first case is for work and energy. The unit for work is the joule. Work is done when a force (newtons) is applied through a distance (meters). Work is calculated as the force times the distance. One joule of work is done when a force of one newton is applied through a distance of one meter. For work we do not use the units Nm, instead we abbreviate this as the joule (j)
The second case is for torque. Torque is a force that causes an object to turn or rotate. The unit for torque is the newton-meter. Torque is calculated as the force times the lever arm. The lever arm is the distance away from the pivot point that the force is applied. One newton-meter of torque is when a one newton force is applied to an object 1 meter from the pivot point.
