Recognize and represent vector quantities

What you'll learn

1. Distinguish vector quantities (having both magnitude and direction) from scalar quantities (having magnitude only).
2. Represent a vector quantity using a directed line segment with an arrowhead.
3. Identify the initial point and terminal point of a directed line segment.
4. Use appropriate symbols for vectors (**v**, $\vec{v}$) and their magnitudes (|**v**|, ||**v**||, v).
