Question

Explain the term Speed?

Answer 1

Speed:

1. The rate of change of position of an object in any direction.
2. Speed is measured as the ratio of distance to the time in which the distance was covered.
3. Speed is a scalar quantity as it has only direction and no magnitude.
4. Speed is given by $speed\left(S\right)=\frac{dis\tan cetravelled\left(D\right)}{timetaken\left(T\right)}$
5. The SI unit of speed is $\raisebox{1ex}{$m$}\!\left/ \!\raisebox{-1ex}{$s$}\right.$
