Question
Explain multiplication of a vector by a scalar.
✓
Answer
When a vector $\overrightarrow{ A }$ is multiplied by a scalar ‘s’, it becomes ‘s $\overrightarrow{ A }$' whose magnitude is s times the magnitude of $\overrightarrow{ A }$. The unit of$\overrightarrow{ A }$ is different from the unit of ‘s $\overrightarrow{ A }$’.
For example,
If$\overrightarrow{ A }$ = 10 newton and s = 5 second, then s$\overrightarrow{ A }$ = 10 newton × 5 second = 50 Ns.
For example,
If$\overrightarrow{ A }$ = 10 newton and s = 5 second, then s$\overrightarrow{ A }$ = 10 newton × 5 second = 50 Ns.
