What is a unit of torque?

• A. Newton
• B. Joule
• C. Newton meter
• D. Pascal

Answer: (C)

Torque is a measure of the rotational force applied to an object. It reflects both the magnitude of the force and the distance from the pivot point (or axis of rotation) at which the force is applied. The unit of torque is derived from the units of force and distance. The standard unit of force in the International System of Units (SI) is the Newton, and the unit of distance is the meter. Therefore, when these two units are combined to describe torque, the result is the Newton meter (N·m). This means that one Newton meter is the torque resulting from a force of one Newton applied at a perpendicular distance of one meter from the pivot point. The other options represent different physical quantities: a Newton measures force, a Joule measures energy, and a Pascal measures pressure. None of these directly represent the concept of torque, which specifically involves the interaction of force and distance in a rotational context. Thus, the most appropriate choice for a unit of torque is the Newton meter.
