Question
Explain representation of a vector graphically and symbolically.
✓
Answer
- Graphical representation:
A vector is graphically represented by a directed line segment or an arrow.
eg.: displacement of a body from P to Q is represented as P → Q. - Symbolic representation:
Symbolically a vector is represented by a single letter with an arrow above it, such as $\overrightarrow{ A }$.
The magnitude of the vector $\vec{A}$ is denoted as $|A|$ or $|\vec{A}|$ or $A$.
