Difference between Speed ​​and Velocity

Speed and velocity are two absolutely different terms that are used to describe the relationship between the distance traveled by a body and the time taken to cover that distance. the basic difference between Speed ​​and Velocity is that speed refers to the distance covered by a body or object in a determined time and is calculated by taking the distance traveled and dividing it by time. speed is a scalar quantity while the length of time it takes for an object to travel in a certain direction is known as velocity. due to the specified direction or sense of motion, it is a vector quantity.

Difference between Speed ​​and Velocity in Tabular Form




Speed is a scalar quantity that represents the distance traveled by a body in a given time.Velocity is a vector quantity that represents the displacement of a body in a given time interval.


  • It involves the distance traveled and the time elapsed.
  • It is a scalar quantity.
  • It is always positive.
  • It involves the displacement of a body in one direction.
  • It is a vector magnitude.
  • It can be negative or equal to zero.


Speed ​​= distance traveled / time elapsed.Speed ​​= displacement / elapsed time.


It is obtained by dividing the distance traveled by the elapsed time.It is obtained by dividing the displacement by the elapsed time.


Scalar: described only with the use of numerical units.Vector: Described with the use of numerical units and direction.

What is speed?

Speed is a relationship between the distance of an object and the time taken by this object used to travel or cover the distance. this s time can be measured in different ways such as Meters, kilometers, knots, or miles, per hour or per second. so, speed can be expressed as distance and time. since it has no direction and only magnitude. hence, it is characterized as a scalar quantity.

to cover a distance during a specific interval of time is called speed. it can only be given in a positive value.

Characteristics of Speed

  • Speed describes the distance traveled and the time taken to do so
  • It shows always a positive value.
  • It is a scalar quantity.
  • The average speed results from the division between the distance and a time interval.

Medium of Speed

the average speed is the result of the distance traveled by an object during a given time interval. For example, when Usain Bolt set the world record for the 100-meter dash in 9.58 seconds, his average speed was 10.44 meters per second.

What is Velocity?

Velocity is the ratio between the distance traveled by an object and the time it takes you to cross it towards a direction-specific. it refers to the positional change of an object, from an initial reference point, towards the place to which this object has moved (the endpoint of the movement), and the time it has taken to do so.

As it is a quantity that also determines the direction in which the displacement occurs, speed is considered a vector quantity.

Speed ​​is measured in meters per second (m / s, according to the International System of Units), by direction.

In this sense, for an object to have a constant speed, it must travel in a constant direction for a certain amount of time. Any change in direction will simply be variations in speed.

Characteristics of Velocity

  • Velocity is changing an object’s position in a specific direction in a given time interval.
  • It shows positive, negative, or even null (zero) values.
  • It is a vector magnitude quantity.
  • Average velocity involves the displacement between the time interval.

Average Velocity

The average Velocity is the displacement of an object covered from one position to another in a given time interval. since, velocity is concerned with displacement so, if an object is at the same position in a given time interval its velocity is counted as zero. in this way, the magnitude of the velocity can also be negative.

Examples of Speed and Velocity

A better way to understand the difference between Speed ​​and Velocity is to give some real-life examples. suppose that an object is moving 500 Km to the south at the speed of 80km/h. since it has a speed of 80km/h in the north direction.

On the other hand, if instead of going north it follows a circular path at 100 km / h for an hour, ending at the same point where it started, then we will say that its speed has been zero, although with this object it had a speed of 100 km / h.

The speed, then, would be the scalar absolute value of the speed. In this sense, if there is no direction or heading, we will be talking about speed, while if a direction is followed, then it will be about Velocity.
