| 3.2 Angular magnitudes are related to linear ones (I) |
| A body with a
circular movement covers a space (s) which can be measured in metres:
linear space or distance covered, and an angle ( f ) which is measured in radians: angular space.
These two ways of describing displacement are related; the radius of
the movement is decisive in this relation. Observe that at any moment
the length of the arc is related to the space by s = f * r
