**Step-by-Step Text Solution:**

1. **Definition of Moment of Force**: The term 'moment of force' refers to the tendency of a force to cause rotation about a point or axis. It is an important concept in mechanics, particularly in the study of rotational motion.

2. **Components of Moment of Force**: The moment of force is determined by two key components:
- The **magnitude of the force (F)** applied.
- The **perpendicular distance (R)** from the axis of rotation to the line of action of the force.
