Question

Define speed???????​

Answer 1

$\huge\ \pmb{\blue{«\: คꈤ \mathfrak Sฬєя \: » }}$

In everyday use and in kinematics, the speed of an object is the magnitude of the change of its position; it is thus a scalar quantity.

$\sf \pmb {SI \: unit: m/s, m s { }^{ - 1} }$

$\sf \pmb {Dimension: L T {}^{ - 1} }$

Answer 2

Speed can be thought of as the rate at which an object covers distance. A fast-moving object has a high speed and covers a relatively large distance in a given amount of time, while a slow-moving object covers a relatively small amount of distance in the same amount of time.
