Question

What is ms^-1 in terms of velocity? It's a unit right, but whats the -1 for?

Answer 1

\[Example: 2ms ^{-2}\]

Answer 2

sorry... I meant to write -1

Answer 3

In fact formula of velocity is \[v = \frac{ d }{ t }\]

Answer 4

And "d' stands for displacement or distance... SI unit of d is meter... and " t " stands for time.. SI unit of time is Second...

Answer 5

yeah but like the velocity can be written km/h or m/s but why ms^-1

Answer 6

velocity in terms of unit is.. \[v = \frac{ meter }{ second }\]

Answer 7

but why the -1?

Answer 8

So unit of velocity is \[\frac{ m }{ s }\]

Answer 9

oh!!! haha!! lightbulb moment

Answer 10

\[ms ^{-1}\]

Answer 11

you can also write \(km.h^{-1}\), the negative power is not restricted to \(m.s^{-1}\)

Answer 12

got it. Index laws

Answer 13

thanks!!!

Answer 14

\(\textbf{anything}^{-1} = \cfrac{1}{\textbf{anything}}\)

Answer 15

can't believe I forgot that!!

Answer 16

You're welcome.
