Answer:
The joule (symbol: J) in SI and metric systems, and the foot pound-force in customary systems.
Step-by-step explanation:
Work is the force applied over some distance; that is, newtons per square/cubic meter. Therefore, work is calculated by diving the force (newtons) by the distance (meters). The resulting unit would normally be written down as N/m², but for brevity's sake, we just call it the joule.
