## What is speed?

The time rate of change of position of the object in any direction is called the speed of the object, typically metres per second, kilometres per hour or miles per hour for example. The Speed at which an object travels through the air is its velocity. The speed at which an object travels can be calculated by dividing the distance travelled by the time taken.

◉ 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

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

## Types of speed

**1. Uniform speed or Constant speed** If an object covers equal distances in equal intervals of time, then its speed is called uniform speed or constant speed.

**2. Non-uniform speed or Variable speed.** If an object covers unequal distances in equal intervals of time, then its speed is called non-uniform speed or variable speed.

**3. Average speed** The ratio of the total distance travelled by the object to the total time taken is called the average speed of the object.

**4. Instantaneous Speed** The speed of a particle at any instant of time is known as its instantaneous speed.

## 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.
