Question
Explain addition of vectors.
✓
Answer
- The addition of two or more vectors of same type gives rise to a single vector such that the effect of this single vector is the same as the net effect of the original vectors.
- It is important to note that only the vectors of the same type (physical quantity) can be added.
For example, if two vectors, $\overrightarrow{ P }$ = 3 unit and $\overrightarrow{ Q }$ = 4 unit are acting along the same line, then they can be added as, $|\overrightarrow{ R }|=|\overrightarrow{ P }|+|\overrightarrow{ Q }|$
$|\overrightarrow{ R }|=3+4=7$
[Note: When vectors are not in the same direction, then they can be added using triangle law of vector addition.]
