Final answer:
The SI unit of moment of force is the Newton meter (Nm), representing force applied at a distance from a pivot point.
Step-by-step explanation:
The SI unit of moment of force is the Newton meter (Nm). This unit can be understood by considering the SI unit of force, which is the Newton (N), fundamentally breaking down to kg·m/s², as per Newton's Second Law, F = ma, where mass is in kilograms (kg) and acceleration is in meters per second squared (m/s²). When looking at a moment of force, which is also known as torque, it involves applying a force applied at a distance from a pivot point; therefore, it is a measure of rotational force. The SI unit reflects this as force times distance, resulting in Nm.
