What is the unit of metric measurement for work?

The unit of metric measurement for work is the Joule. In the metric system, work is defined as the product of force and distance. When a force is applied to an object and that object moves in the direction of the force, work is done. A Joule is defined as the amount of work done when a force of one newton moves an object one meter in the direction of the force.

This unit effectively captures the relationship between force, motion, and energy in a straightforward measurement, making it integral to understanding concepts in physics and engineering, especially in contexts where forces are applied and work is performed, such as in industrial settings.

The other units provided serve different purposes: the Watt is a unit of power (the rate of doing work), the Kilopascal is a unit of pressure, and "Power" itself is a concept rather than a unit. Thus, the Joule is the only option that correctly represents the unit of measurement for work.
