◉ The SI unit of speed is ms-1 but sometimes the speed of an object is expressed in Km/hr.

◉ The dimensional formula of speed is [M° L T-1].

◉ Speed is a scalar quantity i.e., it has magnitude only but no direction.

◉ The speed of an object can be positive or zero but not negative.

## Speed formula

you can use the following formula

Speed(v) = Distance travelled (s) / Time taken (t)

## How to use a speed calculator?

Enter the distance in meters into the input box, and then enter time second by second into another input box. Once those are both filled in, click on the calculate button to get the speed value in the answer box.
