Difference between Speed and Velocity
Speed and velocity are two absolutely different terms that are used to describe the relationship between distance traveled by a body and 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  Velocity 
Definition  
Speed is a scalar quantity that represents a 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. 
Characteristics  


Calculation  
Speed = distance traveled / time elapsed.  Speed = displacement / elapsed time. 
Half  
It is obtained by dividing the distance traveled by the elapsed time.  It is obtained by dividing the displacement by the elapsed time. 
Magnitude  
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 Meter, kilometer, knots, or miles, with per hour or per second. so, speed can be expressed as distance and time. since it has no direction and has the 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 distance traveled by an object during a given time interval. For example, when Usain Bolt set the world record for the 100meter 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 directionspecific. 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 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) value.
 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 about displacement so, if an object is at the same position in a given time interval its velocity is count 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 reallife 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 to 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.
