Vector
Vector quantities are often represented by scaled vector diagrams.
Vector diagrams depict a vector by use of an arrow drawn to scale in a
specific direction. Vector diagrams were introduced and used in earlier
units to depict the forces acting upon an object. Such diagrams are
commonly called as free-body diagrams.
An example of a scaled vector diagram is shown in the diagram at the
right. The vector diagram depicts a displacement vector. Observe that
there are several characteristics of this diagram that make it an
appropriately drawn vector diagram.
**Scale : as we do keep scale while drawing a graph.
Vector = scalar(magnitude) + direction
**Scale : as we do keep scale while drawing a graph.
- a scale is clearly listed
- Head of the vector always points towards the Direction.
- Magnitude of the vector is shown by the length of the vector. In this case, the diagram shows the magnitude is 20 m and the direction is (30 degrees West of North).
Vector = scalar(magnitude) + direction
