The first question in mind is what is the difference between speed and velocity whenever it comes to measuring motion. These two terms may be used for distance, time, and direction but the meaning is different. So it is important to know what is the difference between them to understand them better.
What Is the Difference Between Speed And Velocity?
Let us first understand what velocity and speed mean.
Velocity: Velocity means the rate and direction that when the object moves. You can say that speed is a vector.
Speed: Speed means the rate at which the object moves in a path. You can say that speed is a scalar value
In short, I would say that the main difference that can describe the difference between speed and velocity definition is that speed defines how fast has the object moved whereas velocity defines the speed as well as the direction in which the object has movies
Different Type Of Speed And Velocity Definition
The different definitions between Speed and Velocity are
Speed: Speed is defined as the magnitude of velocity. Or you can say the rate at which the object changes its position.
Velocity: Velocity is defined as the measurement done by the rate at which the object changes its position and also the direction.
Different Type Of Speed And Velocity
There are 2 types of speed and 4 types of Velocity. Let us understand t
Types Of Speed

Uniform Speed
Uniform Speed means the distance that is traveled and where the distance and the time are taken to travel is the same.

NonUniform Speed
Uniform Speed means the distance that is traveled and where the distance and the time are taken to travel is not the same.
Types Of Velocity

Constant Velocity
The Velocity that does not change its direction and speed means moving in the same direction that is in a straight line is called constant velocity.

Changing Velocity
The Velocity that changes as the direction changes or the speed changes is known as constant velocity.

Instant Velocity or Instantaneous Velocity
The velocity where everything changes that is the time, the speed as well as the direction changes then it is known as Instant or Instantaneous Velocity

Terminal Velocity
When the object is taken over by gravity that means it falls downs through the atmosphere and gravity is known as Terminal Velocity.
What Is The Main Difference Between Speed And Velocity?
Speed  Velocity 

Speed means the rate of changing of motion  Velocity means the rate in which the object has changed its position 
Speed is the distance that an object travels and is measured in unit time  Velocity is the placement of the object that changes that is measured in unit time 
Speed is measured in scalar in quantity  Velocity is measured in vector in quantity 
Speed means how fast an object moved  Velocity means how fast the object is moved as well as the direction in which the object moved 
Difference Between Speed And Velocity Formula
Here is the formula to calculate both speed and velocity
Speed = distancetime
Velocity = Displacement Time = FinalPosition – InitialPosition Time
Comparison Between Speed And Velocity
Here let’s compare some points between speed and velocity.
 Speed means the distance that is covered in units of time and on the other hand velocity is the displacement that is covered in units of time. Here distance covered means the distance that is measured but the displacement means the distance and also the position of the object that is calculated.
 Speed is known as scalar quantity whereas velocity is known as vector.
 Speed will only let you know how fast the body moves whereas velocity will tell you the speed and the direction of the body.
 Speed can be described as a change in distance and velocity can be described as a change of displacement.
 The speed can be zero but the velocity can never be zero. But Velocity can be positive or negative.
The only similarity between Speed and Velocity is that these both are measured in m/s.
FAQ
What are the three differences between speed and velocity?
Here are the three differences between Speed and Velocity
Speed  Velocity 

Speed means the rate of changing of motion  Velocity means the rate in which the object has changed its position 
Speed is the distance that an object travels and is measured in unit time  Velocity is the placement of the object that changes that is measured in unit time 
Speed is measured in scalar in quantity  Velocity is measured in vector in quantity 
Speed means how fast an object moved  Velocity means how fast the object is moved as well as the direction in which the object moved 
What word best describes the difference between velocity and speed?
The words that best describe the difference between velocity and speed are distance and displacement.
What is the difference between speed and velocity kid definition?
The main difference that can describe the difference between speed and velocity definition is that speed defines how fast has the object moved whereas velocity defines the speed as well as the direction in which the object has movies

The similarity and differences between speed and velocity are
The similarity between speed and velocity
The only similarity between Speed and Velocity is that these both are measured in m/s.
Difference between speed and velocity

Conclusion
The two terms are speed and velocity are confused but they are completely different. Although both are calculated in the unit of time the definition is very different. So you must understand both the terms must be understood properly before using them to calculate or use them. The above article is completely dedicated to the difference between these two terms.
