What is the unit of measure for a moment of force?

The unit of measure for a moment of force, often referred to as torque, is the Newton metre. This unit arises from the definition of torque as the product of the force applied and the distance from the pivot point at which the force is exerted. Torque measures how effectively a force can cause an object to rotate around an axis.

In the case of the Newton metre, it combines the force unit (Newton) with the distance unit (metre). Therefore, when you apply a force measured in Newtons at a distance measured in metres from a pivot or axis, the resulting measurement of the moment of force is expressed in Newton metres.

Other options, such as the pound, joule, and pascal, represent different physical quantities. The pound is a unit of weight or force, the joule is a unit of energy, and the pascal is a unit of pressure. These units do not apply to the concept of torque, which specifically requires a force acting at a distance to create rotational motion.
